Copilot Studio - General

Language upload fails in copilot

Posted on by 7

Hey Guys,

It seems like that microsoft made some updates to copilot studio yesterday.

I downloaded the .resx files for the different languages and updated some phrases. when trying to upload them again I get this error Message: "There was a problem during the file upload."

Did someone experience the same or does know a fix for this?


Best Regards

    This is still an issue, thankfully the workaround of deleting the language and adding as new helped.

    In my case it wasn't enough, I had to remove the cards code inside json file to be able to upload it 😞
