ERROR: Null state detected for source ... - data discarded

Reason:

Resolution:

Ensure that the system generating the messages for that source is submitting valid messages in a valid format and with valid content.

Tips:

• Are the messages in valid format?
• Do the messages contain valid content?
• Is the port configuration correct?
• Find the port used by the source by using the view star$sources
• Test the port configuration using the test_port function with a sample message.
