Description

When trying to set property Project ID (processor ConsumeGCPubSub, Bundle org.apache.nifi - nifi-gcp-nar) with an EL value

Error message occurs as below

The problem does not occur if using plain text value for the same property.

Investigating this processor's source code, I found the cause for this issue (lastest source code at main branch): https://github.com/apache/nifi/blob/8d53f5d0c91a4e759ea7033bb4d0143ba96d2c21/nifi-nar-bundles/nifi-gcp-bundle/nifi-gcp-processors/src/main/java/org/apache/nifi/processors/gcp/pubsub/ConsumeGCPubSub.java#L182
The same problem happens with processor PublishGCPubSub:
https://github.com/apache/nifi/blob/8d53f5d0c91a4e759ea7033bb4d0143ba96d2c21/nifi-nar-bundles/nifi-gcp-bundle/nifi-gcp-processors/src/main/java/org/apache/nifi/processors/gcp/pubsub/PublishGCPubSub.java#L212
