ldproxy4: Styles fails to render or render with errors

[Sverre-Iversen]

Example 1 - In "Styles to render the data in maps" | "Web map using the style" FAILS:
The map starts to render with styling, but a lot of Java errors appears in the log.

Example 2 - "Access the data" | "<Collection name>" or "Access the data as tiles" FAILS:
ERROR:
Could not access style 'http://localhost:7081/ankringsforhold/styles/ankringsforholdomr?f=mbs', falling back to style 'NONE'.
Response code: '404'. Message: Not Found

But if I copy the URL 'http://localhost:7081/ankringsforhold/styles/ankringsforholdomr?f=mbs' and paste it in a new tab, the JSON-file will be shown correctly. So is the error a bug?

Example 3 "Access a web map with the data" - FAILS:
The map starts to render with styling, but a lot of Java errors appears in the log.
ERROR [2024-04-17 13:48:58,174] ankringsforhold - Null pointer to PROJ object.
ERROR [2024-04-17 13:48:58,175] ankringsforhold - Server Error with ID a22ba3f91e7af72e: Null pointer to PROJ object.

The style is defined in the service file as in earlier versions:

    - buildingBlock: HTML
      enabled: true
      defaultStyle: ankringsforholdomr
