SM59 Connection Test Error

[#1]

Hello.

I am getting an error when trying to connect to the AVALA Tax service in SAP BTP using the OAUTH client profile.

SM59 Destinations Type G  (HTTP External):
AVLR_AVATAX_ADDRESS
AVLR_AVATAX_GLOBAL
OAuth Profile : SAP_COM_0249_PREM
Error Observed : Create Failed

Testing Details:
T-code: SE38
Program Name: OA2C_GENERIC_ACCESS
HTTP Client Selection: SM59 Destination

HTTP Client Selection: URL option

Once SAP enables the required connectivity, the SM59 test should work as expected.

I would like to hear the opinions of seniors who can help me solve the above problem.
