The lemlist API failed to provide the CSV report to Lembot.
Lembot needs this CSV file (your raw campaign data) to format it and import it into Google Sheets. Unfortunately, this is a lemlist-side issue.
If the download works: The issue might be temporary. Try running your bot again later.
If the download fails too: This confirms lemlist is having trouble generating the report for this campaign. Contact the lemlist support team here: https://help.lemlist.com/en/
They'll be able to investigate why the report isn't generating properly.
