Hi @GyorgyVARGA,
The error message suggests that the fetch call being made to the Google Maps API is being blocked. Although you have already allowed scripts to be loaded from https://maps.googleapis.com
, in this case, you also need to allow fetch calls to be made for that same domain, e.g:
permissions:
external:
fetch:
client:
- https://maps.googleapis.com
See https://developer.atlassian.com/platform/forge/manifest-reference/permissions/#fetch for more details
Hope that helps!
