Make sure to log error in findObjectsForSrc()

It is hidden right now if there is an error in configured named
fields and index. Lets log the error and return the current state
of requests.

With this the findObjectsForSrc() will exit with an hidden error
like:

"error": "Index with name field:.spec.ksmTls.caBundleSecretName does not exist"
