Map is not displayed !

[dondonms]

Hi, thank you for developing this plugin.
Sorry, this is not a new question, but I hope you can answer it.

I pasted the GoogleMapAPI I created in google_static_map_api_key.yaml, started rviz and added "OverlayGpsDisplay".

However, when I select "/fix", "/ublox/fix" or "/ublox/hp_fix" in "Topic", GoogleMap is not displayed.
When I select "/ublox/fix" or "/ublox/hp_fix", the status shows "map image file does not exist.

I am currently experimenting with the free period of GooglePlatform. Any solutions to the above problem would be greatly appreciated.

Thank you.
