Wails: Error when either running `wails serve` or running executable generated by `wails build`

[psidex]

Description

An error message pops up when I try to run the executable generated by wails build.

Dismissing this message by either pressing "yes" or "no" closes the error window and the normal window is just a blank white box.

In a similar vein, running wails serve gives an error - https://pastebin.com/4JBWNeDY.
Unfortunately the output is not too helpful.

To Reproduce

Steps to reproduce the behaviour:

1. Create a new project using wails init
   
   
   
   • This was tested with both React and Vue project templates
   
   
2. cd to the project directory and run wails build
3. Run the projectname.exe file
4. See error

OR

1. Create a new project using wails init
2. cd to the project directory
3. Run wails serve and the stop it
4. Interestingly enough, the first time wails serve is run it works fine. It's only the second time and onward that it breaks, so run wails serve again
5. See error

Expected behaviour

The app opens and displays the default wails project page.

System Details

| Name | Value |
| ----- | ----- |
| Wails Version | v0.18.13-pre |
| Go Version | go1.13.1 |
| Platform | windows |
| Arch | amd64 |
| GO111MODULE | (Not Set) |
| GCC | 4.8.3 |
| Npm | v10.16.3 |
| Node | 6.9.0 |

Additional context

This is basically 2 issues in one but I think they are possibly related?

Also just as a side note I have switched over to tdm-gcc and this still happens.

Hi. Can you please test with the latest prerelease? wails update -pre

Thanks!

I'm on v0.18.13-pre and it says that's the latest prerelease?

[FriendlyUser]

I am getting the same error

[leaanthony]

Update: I now have serve working correctly, even through IE. However the built app still throws the same error, which is weird as it's the same code going to the same web engine. Still debugging.

Please check out the file attached to this comment(https://github.com/wailsapp/wails/issues/259#issuecomment-547284087).
webview_fix_ie_compat_mode() and more functions fixed.

I'm also having this issue. I tried the patch above, and I don't know if I built wails wrong but it didn't seem to resolve the issue for me

[leaanthony]

Please let me know if v0.18.15-pre fixes this. wails update -pre. Thanks!

[FriendlyUser]

Didn't fix it for now

[leaanthony]

Are you using Windows 7 or 10? It's working fine for me on Windows 10.

Tested on Win 10, wails serve is now working fine for me.

[FriendlyUser]

@leaanthony wails serve has always worked for me, wails build is still failing for me.

[leaanthony]

Hi. Please run wails update -pre to get v0.19.0-pre2. Let me know if this fixes your issue. Thanks

[FriendlyUser]

Still failed for me

On Wails v0.19.0-pre2 - Building Application

Didn't update or regenerate go.mod

[lukasvosyka]

Hi Lea,

for me wails 0.190-pre2 now works also with the built .exe on Windows 10. But I had to recreate (wails init) a new project. After that it seems to work. Thanks!

[leaanthony]

Awesome. Due to dependency versioning, you will need to either update
go.mod or regenerate.

Worked for me when I reinit the wails project.
