@amulyavarote once dapr/dapr#4288 is merged and an RC is created, we can update the version of RC in CLI and use that here ... till then the E2E will fail here. Since CLI works with already released or release candidate versions of daprd available in GitHub (testing dapr init)and not directly building from dapr/dapr codebase as supported by SDKs.

Please add E2E tests exercising the api log level flag ... in tests/e2e/standalone ...
