Intermittent failure of tests

[JSAssassin]

Tests https://github.com/w3c-ccg/status-list-2021-test-suite/blob/main/tests/20-verify.js#L94 and https://github.com/w3c-ccg/status-list-2021-test-suite/blob/main/tests/20-verify.js#L124 experience intermittent failures for DB.

Behavior:

The assertion for the revoked/suspended VC status sometimes fails because, in some cases, the status remains unchanged after the update.
Other times, the status is updated to true, but the shouldFailVerification assertions fail due to inconsistencies in the response, where it sometimes contain a result and sometimes lacks error data.

Note:

The tests pass successfully when using localhost endpoints on the main branch for both the issuer and verifier services (v20.1.2 and v16.1.2, respectively). So, I am unable to replicate the problem locally.

Also tried creating new QA DB issuer and verifier instances (https://github.com/w3c-ccg/vc-api-test-suite-implementations/compare/update-db-status-list-implementation) that uses the latest versions of issuer and verifier(v20.1.2 and v16.1.2), that didn't fix the issue though.
