reduce(
fn!append,
{},
a!applyComponents(
function: rule!CTR_transactionDetailsEntryCustomerSummarySections(customerDetails:_, removeCustomerDetails: local!removeCustomerDetails, modifyCustomerDetails: ri!modifyCustomerDetails, AMLBoolean: ri!AMLBoolean, formOutcome: ri!formOutcome),

    I have reviewed the jboss1-stdOut.log and the only description offered is: "ERROR com.appiancorp.rest.shared.AppianExceptionMapper - Internal Server Error on REST API invocation.23:18:15,457 INFO [stdout] (ajp-/0.0.0.0:8009-13) com.appiancorp.process.expression.ExpressionRuntimeException$AppianExceptionProvider: Expression evaluation error in rule 'ctr_transactiondetailsentryreviewandsubmit' at function 'reduce' [line 35]: (APNX-1-4198-000)".

    Any assistance would be greatly appreciated!

    Are there any 'Caused by's in the stack trace of the error you mentioned? These should give some more information as to what is going wrong.

    Tom, thanks very much for the reply! The following error displays just before the error I added previously

    An ArrayIndexOutOfBoundsException suggests you may be passing too many or not enough arguments to a function. If this is not the case, can you attach the complete log so that I can look in more detail?

    Hello Tom. I have been troubleshooting the issue and I do not believe the issue to be the result of passing too many or not enough arguments. I am attaching the complete log as requested. I sincerely appreciate your time and assistance!
