Could not create user agent

Grafana
1

Hi,

I updated Grafana from version 11.3.1 to Version 11.3.8+security-01 (commit: bd5b3f533cfcfa7588d81645c860971f06e132e6, branch: HEAD).

now in the log I have these repeated errors:

logger=base.plugin.context t=2025-10-14T09:57:37.127283419+02:00 level=warn msg="Could not create user agent" error="invalid user agent format"
