Hi! I have the most recent snap installation of Rocket Chat - 0.61 and I wanted to import Slack data. While users and channels are imported without any problems, the process stops at 1500/84000 and messages are not imported. Importing ends with success status. This is what is in the logs. ``` [34mI20180612-08:29:27.660(2) Exception in callback of async function: Error: File exceeds allowed size of -1 B.

Do you have any pointers what can be the problem? ---

You say 61 we are on 0.65.1 typo? Just checking before diving too far into it 🙂 ---

Yeah, it’s a typo. Sorry. Rocket.Chat Version: 0.65.1 ---

I’m not that familiar with slack import, but maybe try setting the file size limit super high during the import? ---

That’s actually set when the import runs, according to the logic it was supposed to bypass the upload limit. @rodrigo.nascimento here is yet again another item of this, it needs to be fixed.

@pglimos please add your details here: [https://github.com/RocketChat/Rocket.Chat/issues/10278](https://github.com/RocketChat/Rocket.Chat/issues/10278) when this bug is closed it _should_ be resolved ---

+1 here - our import from Slack stopped after 3/4 of the channels. It’s too late for us now hence we already used the empty channels and reimporting/merging is not an option? ---

Did it stop with the same error as above or a different error?
