"An error occured" in BOARD Web - How to determine the cause

Stephen Kirk

Hi,

 

I am currently completing some user acceptance testing with an application I have developed in BOARD 10.5.1 (web) and the user today experienced an error. They were making some data entry and clicked a 'Save' button (which has a procedure sitting behind it) the following popped up after appearing to do some processing (this is what the user has said):

 

 

My question is more general - when an error does occur in BOARD web, it has a reference code. Is there anyway this can be used to determine the cause of the error?

 

If so / if not - how can I track how the error may have been caused?

 

Thanks,

Stephen

I have now found that it references the error in the BOARD web log. The below is my error, I was wondering if anyone could explain what it could mean?

 

2019-10-09 14:48:58.399 +08:00 [Error] LogEntry { Feature: NotDefined, Username: "ERose", ConnectionId: "e519fd92-d4e3-47b5-83c1-4509153e33f5", Message: "https://board.mlgoz.com.au/api/Screen/CommitMultipleDataEntry", Exception: InvalidOperationException { Message: "Collection was modified; enumeration operation may not execute.", Data: [DictionaryEntry { Key: "MS_LoggedBy", Value: [ApiExceptionLogger {  }] }], InnerException: null, TargetSite: Void ThrowInvalidOperationException(System.ExceptionResource), StackTrace: "   at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)

 

I think the important part is: "Collection was modified; enumeration operation may not execute.",

 

Thanks,

Stephen
