Start by reproducing the POST request shown in the issue against the /v1/functions/.../invocations endpoint with the listed Docker and CentOS 7 environment. Trace how the X-easyfaas-Account-Id header is checked against the invocation caller, then inspect the related authentication or invocation tests if available. Done means the request authenticates consistently and no longer returns InvalidInvokeCallerException.
