Redfish API error "msg": "Status code was 405 and not [200]: HTTP Error 405: Method Not Allowed"

Hi,
Using Ansible playbook trying to run a diagnostic test against the Dell poweredge server using iDRAC.
However,on POST to initiate the diagnostic, encountered an error

"msg": "Status code was 405 and not [200]: HTTP Error 405: Method Not Allowed",
"odata_version": "4.0",
"redirected": false,
"server": "Apache",
"status": 405,
"strict_transport_security": "max-age=63072000; includeSubDomains; preload",
"url": "https://xxx.corp/redfish/v1/Managers/iDRAC.Embedded.1/DellLCService/Actions/DellLCService.RunePSADiagnostics",
"x_frame_options": "DENY"

If we use curl to test the Redfish API it does not through the error.

curl -k -u "XXXX:XXXX" -v -H "Content-Type: application/json" -d "{"RebootJobType": "GracefulRebootWithoutForcedShutdown", "RunMode": "Express"}" https://xxxx.corp/redfish/v1/Managers/iDRAC.Embedded.1/Oem/Dell/DellLCService/Actions/DellLCService.RunePSADiagnostics
