Saving Failed

[lausserl]

Hi, I recently installed the update again after the fix for netbox version > 3.0.0, thank you for that.
I discovered an issue when I want to safe the view now. The only log that I can find is the following:
Unsupported Media Type: /api/plugins/nextbox-ui/savedtopologies/
Maybe the text from the "Save Current View" field is not correctly assigned to the POST statement? The POST log looks like this:
"POST /api/plugins/nextbox-ui/savedtopologies/ HTTP/1.1" 415 100
My knowledge here is limited though, I hope you can help me.
