A Timer Event with a valid expression-based delay throws an error when activated:
There is a problem with the process "Error on Timer"Problem: An invalid expression has been encountered.Details: ERROR:EVAL:@reason=indexRecommended Action: Check the expression including any function requirements and resume.Priority of this problem: High Priority
This error occurs when keywords are used to pass in parameters to the expression used to specify the timer delay, for example:
rule!exampleRule( time: now(), timezone: "EST")
Timer event delays not supporting keyword parameters is a known limitation of the Appian product.
Remove the keywords from the parameters passed into the timer delay expression, for example:
rule!exampleRule( now(), "EST")
This article applies to all versions of Appian.
