But it is throwing below
BODY @EvaluateExpression(STRING_ENCODED,<at>Value<openparen>_job_id<closeparen><lf><at>Value<openparen>_timeStarted<closeparen><lf><at>Value<openparen>_timeFinished<closeparen><lf>,FMEServerNotifier_2) OUTPUT OUTPUT FEATURE_TYPE FMEServerNotifier_2_OUTPUT OUTPUT REJECTED FEATURE_TYPE FMEServerNotifier_2_<REJECTED>' is incorrect. The parameter to TOPIC must be a constant value, a value-of (&) attribute, or an FME function call
Below is my content for the notification
@Value(_job_id)
@Value(_timeStarted)
@Value(_timeFinished)
Any ideas why this might be happening ?
