Azure Map - Reference Layer URL - doesn't display

Hello Power BI community,

I have been searching for hours, but can find out what's wrong. I am trying to display geojson using Azure Map visual, reference layer.

Why does this file display correctly?

https://raw.githubusercontent.com/Azure-Samples/AzureMapsCodeSamples/main/Static/data/geojson/GpsTra...

But this one doesn't?

https://alexander-simon.de/adflkjweiovoijdf/GpsTrace.json

If I use curl to download both files they are identical (according to fc). 

I use Power BI Desktop Version July 2024.

Same issue if I publish (Service version:13.0.23776.64)

If I click on the i Icon in the Header of the visual I get the message: Unable to load reference layer. Unable to parse file.

 

Any ideas?

Thanks a lot

Alex

Just figured it out by enabling PBI diagnostics:

"Access to fetch at 'https://alexander-simon.de/adflkjweiovoijdf/GpsTrace.json' from origin 'https://ms-pbi.pbi.microsoft.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled."

 

I had to add this to the .htaccess on my web-server:

Header set Access-Control-Allow-Origin "https://ms-pbi.pbi.microsoft.com"
