> Users often encounter an exception when validating certificates which is

> {code}
> Due to phrases like "PKIX path building failed" and "unable to find valid
> certification path to requested target", users often believe this is a file
> path issue and that NiFi cannot locate the truststore. However, the issue is
> actually that no *certificate validation* "path" can be constructed -- i.e.
> NiFi cannot find a chain between the certificate being validated and any
> trusted CA certificate that has signed it (or intermediaries).
> This exception should be caught and a more explicative error message should
> be displayed, with suggestions for how to resolve this issue (usually
> importing the custom CA certificate or self-signed certificate into the
> truststore).
