JSON Syntax Error

Follow

Symptom:

When attempting attempting to run Jobs on a JAMS Agent whose version is older than the JAMS Server (E.g. a JAMS V6.5.38 Server running Jobs on a JAMS V6.2.11 Agent), users may encounter the following error: 

" JSON syntax error, expected '{', '}', or comma "

 

Cause:

This happens if enhancements were added to the Execution Method between versions. If the Server is upgraded to the enhanced version and the Agent is not, there is no way for the older Agent version to know what the Execution Method enhancements on the Server are. When the Agent cannot evaluate a field, it throws the JSON syntax error.

 

Resolution:

Upgrade the Agent to the current JAMS Server Version.
