Unfortunately this is on our side, export service (although works and generates files) returns the error message, both to the API call as well as on the screen. We’re working on it and hopefully will resolve today.
I don’t think it was resolved, it seems to be doing a generic download. The download I got previously for this survey is significantly larger, when I opened the file, I got one record. I hope this is resolved asap and that our data is in no way compromised.
