V3API restricted for Path:/sdpapiv2/project_import Method:POST

Hi,
I want to import MS Project file in SDP MSP project module, but it doesn't work and get error in browser console like this:
  1. V3API restricted for Path:/sdpapiv2/project_import Method:POST
I attached my error screenshot of network console with test.mpp file.

SDP MSP: v10.5.10
DB: MS SQL

Thanks for helping
