Rocket.chat: Slack import does not recognize the source file

[zxweed]

Your Rocket.Chat version: 0.31

The slack export bundle contains JSON-files only, but the servers returns "invalid import file type" error.

[zxweed]

Hello, @graywolf336, @geekgonecrazy. Tell me, please, is there a way to import slack history in it's current format (only json-files)?

[geekgonecrazy]

@zxweed the import expects the zip file that is given to you by a slack export

[zxweed]

@geekgonecrazy, I have tried the zip bundle with same results too:

[zxweed]

there are no error message in the log:

[methods] setupImporter -> userId: Efjsx7m6u4mrfcm7A , arguments: { '0': 'slack' }
[methods] getImportProgress -> userId: Efjsx7m6u4mrfcm7A , arguments: { '0': 'slack' }

[geekgonecrazy]

@zxweed i'm out of ideas on this one. @graywolf336 might know more.

[graywolf336]

@zxweed the file must be an untouched zip file which Slack provides. The importer expects a particular layout of the files insides the zip. Try the importer again with the zip from Slack and get back with us.

[zxweed]

@graywolf336, I have reexport the fresh bundle from slack and try to import it with the same effect - import processes was not initiated.

[graywolf336]

@zxweed mind trying out the newest release? Version 0.30 contains some changes to the slack importer.

[zxweed]

@graywolf336, I have upgrade to 0.30.0 - the problem still exists. The log file contains new line:

[methods] setupImporter -> userId: EA4wsW6TmAf5aPShs , arguments:  { '0': 'slack' }
rocketchat_importer-slack server.coffee:6 Slack Importer ➔ debug Constructed a new Slack Importer.
[methods] getImportProgress -> userId: EA4wsW6TmAf5aPShs , arguments:  { '0': 'slack' }

[zxweed]

0.31 version the same

[graywolf336]

@zxweed Hit me up on the demo server so we can talk about this and get the issue resolved, as we need to look into the file's structure

[AlexandreSNeto]

Same problem here. There are some solution ?

[zxweed]

0.34 - problem exists

[marcocevoli]

on 0.33 and same problem

[ghost]

v.0.37.1. Same problem there.

[zxweed]

0.38 - problem exists

[JSzaszvari]

I have run into the same issue. I found that doing the users first, then
doing the channels one by one seemed to let me get through it till the end.

I needed to restart the server a few times but it eventually all went
through. Very strange.

Sorry I forgot to mention, it worked much better when I was logged in as a
user that did not exist in the slack import. Not sure if related or just a
coincidence though.

I'll give the import a try in a new instance now..

I may still have a export from a few weeks ago when it was all working
fine. I'll try and do a compare as well and report back my findings.

@jszaszvari that might actually be an important piece. I can see things struggling a bit if you are logged in as a user present in the import.

@graywolf336 thoughts? Think this would be a difference between it working and not working?

Hi, I encountered this issue on 0.41.0.

Debugging on my side leads me to event.target.files[x].type being empty.
The check that throw the exception is there in the source.

Hope it'll help

EDIT : I tried various browser just in case... I was surprised of results of mime type detection of zip files :

• Chrome 53.0.2785.116 : KO
• Internet Explorer 11.589.xxx : KO
• Edge 25.10586.0.0 : KO
• FireFox 49.0.1 : OK

I tried with some jpg and png files, it as working. It seems that zip files mime type detection only works on FF.

EDIT 2 : I confirm that I passed this first error on FF for importing Slack exported zip (but encountered #4388 just after).
Seems that import of zip files should not rely on Blob.type, because of mime type detection of the client browser.

[graywolf336]

@whren what would you suggest relying on then?

[whren]

@graywolf336 I'll suggest to rely on file signature + extension if Blob.type is empty.

[engelgabriel]

@graywolf336 is this still a problem?

[graywolf336]

@engelgabriel I think so, I never could replicate it sadly.

[zxweed]

The 0.46 release still have this problem

[graywolf336]

@zxweed Any chance we can talk on the demo server?

[zxweed]

@graywolf336 sure, we have already discussed this issue

[morbidpete]

Same issue here. version 0.48.2 using snap under ubuntu server

[graywolf336]

This should now be fixed in the develop branch, if someone feels like
testing it to verify that would be greatly appreciated!

@graywolf336
I am running the snap container, is there a way to use the dev in snap or do I need to wait?

[graywolf336]

@geekgonecrazy can you answer the above question?

[geekgonecrazy]

@morbidpete if you are in a production environment don't try this. There are a lot of things changing between 0.48.2 and what will be 0.49.0.

Run the following in your dev environment:
sudo snap install rocketchat-server --channel edge

[morbidpete]

@geekgonecrazy No production yet, Just seeing if this is a viable option to replace slack for our use. Thank you for the quick reply.

[morbidpete]

Worked great, thank you all so much for fixing this!

[graywolf336]

Awesome, thank you for trying it out and reporting back! @morbidpete
