Came here to report this very issue. Tried different URLs with same result.

Nativefier: 9.0.4 (installed via HomeBrew)
OS: Mac OSX Mojave 10.14.6

This is my first install of Nativefier. So "Last working" = never.

@zethraeus What is your node and npm version?

[kris-anderson]

@zethraeus What is your node and npm version?

I can also confirm a similar error that happened after upgrading to version 9.0.0 on macOS Catalina 10.15.5

❯ node --version

9.0.0

[TFisicaro]

Tested on Windows 10 1909 with:

> node --version
v12.18.0

> npm --version
6.14.4

> nativefier --version
9.0.0

Same result on macOS Catalina as others have posted above.

[ronjouch]

Thanks for the reports everybody! Very little changed between Nativefier 8.0.7 and 9.0.0, apart from a new major Electron, and Nativefier 9.0.0 works for me under Linux. So, I suspect Electron trouble.

@TFisicaro @zethraeus @schloram @MalEbenSo @kris-anderson, and all the voters of this issue (by the way, thaaaaaaaanks a million for just using the vote button if you want to confirm a bug and have nothing to add :heart:), can you try with an {older, beta} version of Electron? (Nativefier 9.0.0 uses Electron 9.0.4 by default)

• Try passing -e 8.3.2 for the latest Electron 8.x
• Try passing -e 10.0.0-beta.3 for the latest Electron 10 beta

, and report here with:

• Full call of nativefier, with options & url passed, and using --verbose. So, should be nativefier --verbose -e [version] [your other options] [your url]
• --verbose build console output
• Resulting bug/screenshot (as already done a few times above)

--

EDIT also, does the png/ico image reported as un-loadable in your error screenshots (/blah/blah/blah/icon.{ico,png}) actually exist in your filesystem, or not?

--

EDIT maybe related to this?

[bastiotutuama]

Thanks for your input @ronjouch!

Curiously, using, --verbose produces a different error message after the app has been built.

Here is my output for nativefier -i coda.icns -n "Coda" --clear-cache --verbose coda.io:

URL "coda.io" lacks a protocol. Will try to parse it as HTTPS: "https://coda.io". Please pass "http://coda.io" if this is what you meant.

This will lead to the following error on app-opening:

Not using --verbose leads to the error reported first by @schloram.

[MalEbenSo]

When building with electron 8.3.2 the error disappears for me.
The site "dhl.de" works flawlessly.
The site "ebay-kleinanzeigen.de" also starts without the error message. Then the login fails: just white window, nothing happening. This seems to be a different problem.

c) verbose output when building with 9.0.4 and 8.3.2.

[bastiotutuama]

Thanks for the other hint to fallback to an earlier Electron-version @ronjouch.

As also reported by @MalEbenSo using -e 8.3.2 also succeeds to build here. 👍

[mr-mmmmore]

I have the same exact problem as @schloram, trying to generate a GitLab app.

I have tried with various Electron versions (from 5 to 10) and none of them worked for me. From 5 to 8 I only have a white screen when launching the app. For version 9 I have the same error dialog as @schloram. For version 10-beta I have an error report window.

Since the error with Electron 9 reports a problem with the image, I have tried passing the icon when calling nativefier, but to no effect.

Before that I've never encountered this problem with nativefier, but I don't know what version I was using before (probably an 8.x version).

Here are the details.

Command
nativefier --name "GitLab" --maximize --single-instance --internal-urls ".+" -e 8.3.2 -i logos/gitlab.png --verbose "https://gitlab.com/"

Context

• Nativefier: 9.0.0
• Node.js: v14.3.0
• Npm: 6.14.4
• OS: Mac OSX Mojave 10.14.6

Verbose

URL ".+" lacks a protocol. Will try to parse it as HTTPS: "https://.+". Please pass "http://.+" if this is what you meant.
Running in verbose mode! This will produce a mountain of logs and is recommended only for troubleshooting or if you like Shakespeare.

ATTENTION: Using **old** Electron version 8.3.2 as requested. 
It's untested, bugs and horror will happen, you're on your own. 
Simply abort & re-run without passing the version flag to default to 9.0.4

Thanks for your input @ronjouch!

Curiously, using, --verbose produces a different error message after the app has been built.
...

I get this message when I try to relaunch the app after failing to close the app after the original (icon.png) error message.

[sebmartin]

It seems electron wants an icon.png in the Resources dir ... I fixed my Gmail app by doing this:

sips -s format png Gmail-darwin-x64/Gmail.app/Contents/Resources/electron.icns --out Gmail-darwin-x64/Gmail.app/Contents/Resources/app/icon.png

(e.g. generated a .png from the embedded .icns file)

[kris-anderson]

Thanks for the other hint to fallback to an earlier Electron-version @ronjouch.

As also reported by @MalEbenSo using -e 8.3.2 also succeeds to build here. 👍

I can also confirm this works for me.

Passing -e 10.0.0-beta.3 results in the app crashing immediately upon startup with no error message.

Here's the verbose output when I run this without the -e parameter:

It seems electron wants an icon.png in the Resources dir ... I fixed my Gmail app by doing this:

sips -s format png Gmail-darwin-x64/Gmail.app/Contents/Resources/electron.icns --out Gmail-darwin-x64/Gmail.app/Contents/Resources/app/icon.png

(e.g. generated a .png from the embedded .icns file)

Great @sebmartin! This did the trick! Having an icon.png file in the <MyApp-darwin-x64>/MyApp.app/Contents/Resources/app folder removes the error dialog and the app starts normally.

I've used these commands:

$ nativefier --name "GitLab" --maximize --single-instance --internal-urls --icon logos/gitlab.png "https://gitlab.com/" 
$ cp logos/gitlab.png GitLab-darwin-x64/GitLab.app/Contents/Resources/app/icon.png

(since I have the png file already, I don't use sips, I simply copy it where it's needed).

[ialexryan]

Yep, fixing this was as simple as adding an icon.png file to the path indicated by the error message: <name>.app/Contents/Resources/app/!

Command run:
nativefier --name "Asana" "https://app.asana.com" --min-width 750 --min-height 300 --hide-window-frame --single-instance

Error:

Fix:
Used this website to convert the electron.icns file in <name>.app/Contents/Resources/ to a PNG, then renamed that PNG to icon.png and placed it in <name>.app/Contents/Resources/app/. (I assume any PNG would have done the trick.)

@ronjouch Thanks for your reply. -e 8.3.2 seems to work. However -e 10.0.0-beta.3 does not. With this the app doesn't even start and no error message is shown (as described by @kris-anderson here).

EDIT also, does the png/ico image reported as un-loadable in your error screenshots (/blah/blah/blah/icon.{ico,png}) actually exist in your filesystem, or not?

I can confirm like some others before that the icon does not exist but placing a png file by hand in there after the app is being built works. But this of course should not considered a fix. More a temporary workaround 😊

[JAKgit]

Any solution for this except using an old Electron version? Placing a icon.png file is not a solution and does not work all the time.

Thank you very much.

Thank you very much.

Can you provide reproducible steps that show it doesn't work? This is important because otherwise, the likely solution that will be implemented is adding a .png during the build process. So if that's not working, by your claim, the community and authors would benefit from knowing in which situations it doesn't work so they can find a more universal solution.

When I add it manually the path on a Mac cannot be created, otherwise I do understand somethings wrong.

You won't be able to create a folder name like: App Name.app

1. Right click on generated electron app
2. Click on show package content
3. Navigate to Content > Resources > app
4. Copy & Paste icon.png file

Copying the icon.png file into the folder doesn't work for 2 of the apps I've tried. Only the Electron fallback is working.

[sesteva]

That fixed the issue for me

[andrewminer]

Using the -e 8.3.2 option in addition to manually copying the icon.png file into AppName.app/Contents/Resources/apps/icon.png solved the issue for me.

[ronjouch]

This should be fixed in f234473, folks, please try it with a developer build, or wait for the next release.

[simonweil]

I'm seeing this too, when is a new release planned?

@simonweil is is released as 9.1.0

I can confirm that this works like a charm with version 9.1.0. Good job everybody.

[simonweil]

Can confirm too that it's working, thank you so much!
