Symptoms
A 'Lexical Error' is seen in the logs when a workflow is triggered.
Example :
ERROR services.WorkflowService - Exception in workflow service
de.odysseus.el.tree.TreeBuilderException: Error parsing '#{(requestedby.XYZ.collect { it.X}.contains("ABC")) eq true }': lexical error at position 27, encountered invalid character '{', expected expression token
Diagnosis
collect() is a Groovy method
Solution
In the If-Else component of a workflow, a Groovy method like 'collect' can be used. The expression language will then have to be set as 'Groovy'
