Describe the bug
Due to issues with cloud hosted version (#11855) I have been trying to migrate to a self-hosted version, which I have running via hossted on AWS.
When I try to import a application which has been exported from my cloud version, the import fails with the message in console of 'Cannot import a non-text based file.'

I have tested importing back to a cloud tenant and it also shows this issue.

To Reproduce
Steps to reproduce the behaviour:

1. Export an application
2. Create a new application and try to use the exported file to import into the application
3. View error shown in builder and console

Expected behavior
The application should import.

App Export
I will provide this privately is needed.

• OS: Windows 10

Hi Andy. Just to double check, are you using an encrypted export or not? I've just tested both types of export, and they both do correctly import again without an issue. Is your export downloaded properly as a .tar.gz file? If it's encrypted then it should end in .enc.tar.gz.

[andyburgessmd]

@aptkingston I am exporting unencrypted and I get a .tar.gz file. I've tried with and without table data and neither works.

Andrews app-export-1696339861234.tar.zip
Unable to add as tar.gz so had to zip it to get it to be attached.
This a very simple application I have just created - 1 table with 1 row and 1 screen. I have tried to import this to new self hosted tenant and it fails.

[aptkingston]

I'll take a look - thanks for the export.

[aptkingston]

Does that export fail if you import it into cloud as well?

[andyburgessmd]

@aptkingston yes it fails on cloud as well

[aptkingston]

Could you email me the unzipped version, just exactly as you got it from Budibase? That test app is fine.

[andyburgessmd]

Sent, hopefully my outbound email won't block it

[aptkingston]

Looks like it might have been blocked because I didn't receive anything. Are you able to jump on discord?

[andyburgessmd]

Sent from my gmail instead

[aptkingston]

That export works fine for me, tested in both cloud and self host. I really can't think of a reason why this wouldn't work for you, especially in cloud... Do you get that same HTTP 500 with "Cannot import a non-text file" in cloud too?

[andyburgessmd]

@aptkingston I have also just sent the file to my mac and tested from that and it did work. Could this be down to the way that windows is handling the file?

We have a suspicion that this is the case, will need to investigate further.

I tried this on cloud via a Windows laptop and could not reproduce, it worked fine.

Hey @andyburgessmd

I was able to replicate the Cannot import a non-text based file error. I received this when trying to import the app export as provided, i.e. with the .tar.zip format. This is invalid.

App exports must have the file extension .tar.gz to be imported into Budibase.

I was able to import your app by extracting the files from your zip file, and running the following command:

tar -cvzf andrews.tar.gz -C Andrews .

[andyburgessmd]

@melohagan the file was zipped so that it could be transferred, sending the .tar.gz was being blocked.
"Unable to add as tar.gz so had to zip it to get it to be attached."

Could you please upload the .tar.gz file to a cloud drive and send through a download link please?

Imports for me on cloud and self-hosted. Will try on Windows later on.

Hey @andyburgessmd I tried importing that app export you provided on a Windows laptop, and it was fine. I'm not really sure what to suggest.

[andyburgessmd]

Thanks for testing @melohagan. I'm going to raise it with our group IT, I bet they have done something annoying like scan it and strip out something.
I'll let you know what they say if its relevant.
