Rspec Test suite sometimes fails in CI Workflow

[prathamVaidya]

Issue Description

Intermittently, certain specs fail in the RSpec Test Suite during the CI Workflow build.

Reproduction Steps

1. Create a pull request (PR) on the repository, triggering the CI workflow for your PR.
2. Despite the presence of all expected RSpec tests in the repository, some specs may fail unexpectedly.

Expected Behavior

The rspec test suite should ideally maintain consistency in passing without random failures.

Screenshots

Additional Context

Different spec tests fail on each occasion, possibly attributed to occasional failures in the utilized API.
