Upload Problems
Confirm upload support
Section titled “Confirm upload support”Use the installed action’s documented source format and limits. Upload-session support, file size limits, and overwrite behavior remain unconfirmed on this site.
Isolate the source
Section titled “Isolate the source”Try a small non-sensitive file in the supported format. Check whether the source requires browser cookies, a signed-in session, or an expired private URL. Never share that private URL in a public issue.
Check the destination
Section titled “Check the destination”Verify the library’s Drive ID, intended folder, file name, approved access, and behavior when a file already exists.
Before retrying
Section titled “Before retrying”Inspect the target library to see whether the file was written despite a failed workflow run. Record the observed result before repeating an operation.
