IdentityNow BeyondTrust Credential Provider – Secret Fetch Error: “Failed to fetch Managed Account with provided details

I’m facing an issue with the BeyondTrust Password Safe On-Prem Credential Provider in IdentityNow. When attempting to use a secret expression for a connector configuration, IdentityNow throws the following error:

Error while fetching secret secrets://BT%20On-Prem%20Creds%20Provider/systemName%3DDummyAsset%26accountName%3Dsvc_s_idn0001234 :
Failed to fetch Managed Account with provided details. Please check provided secret expression.

Checked from VA connectivity is fine with BeyondTust.
Can anyone suggest what could be the issue?

Issue was there from BT side. Now it is working as expected.
