I've a problem trying to enter any API keys for the additional mapping.
Fresh install (as of 31/12/2025) of Traccar on a Google VM (Debian 12) using the latest version (6.11.1). Server is running and receiving positions from trackers.
Settings > Preferences > Click on Map Overlay drop-down (image 1)
Select any (e.g. Google Traffic).
Attributes form opens asking for Google API key (as expected - Image 2)
But a couple of seconds afterwards the screen refreshes with an error dump (image 3).
When the error occurs, the URL also changes from
/settings/preferences
to
/settings/user/1
Hitting refresh in the browser clears the error, but leaves you on the Settings > Account page.
