Hi @MrPinedita,
if you use the expression ${content.contains("Camunda")} as input entry (i.e. condition) then please make sure that you set the input variable name to content. Note that you can also use this expression as input expression and check the boolean value in the input entry.
However, you can inspect the evaluation result using a decision (table) evaluation listener or the process engine history if you use the DMN engine in combination with the process engine.
There is also an interesting previous topic about this.
Best regards,
Philipp
