Unfortunately, the log message does not show any details about the cause, so we cannot tell what exactly happened.

Suggested improvements to consider:

1. Improve formatting so that the error cause is expanded in the log message (maybe%o will do the trick?) or unwrap the cause from the “fetch failed” error.
2. Wrap the fetch() call in pRetry to handle intermittent failures

/cc @juliangruber This error happened only once, so the issue is not urgent.
