Method to see full Pink Box Error text?

Question

Hello All, 
 
 I'm getting a pink box error message, but the error text is too long so at the end it is adding a "...". My question is, is it possible to somehow see the entire error message anywhere? I've looked in the jBoss logs, but it also ends with the "..." there as well. 
 
 Best, 
 Brenden

This is a "Error Evaluating UI Expression" error so it will not appear in alerts

Agree with brendenh. My bad, use the design_errors Log

So, the error I was getting had to do with a!fromJson() receiving nonvalid JSON but the problem was I couldn't actually see the JSON that wasn't valid because it was replaced with the "...". 
 
I ended up navigating to the rule with the a!fromJson and entering in the exact same parameters in order to see the full error text in designer. Turns out you can't have line breaks (aka. 
) in a JSON string, which I didn't know, so I removed that and it worked!

Hello Brendenh 
 
First I would suggest that maybe the error you are getting somebody else got it before and can identify it by looking at the error, So why don't you post the error? this can give us a hint of what is happening. 
 
With that said, from the forums you can get some ideas: 
 stackoverflow.com/.../how-do-i-stop-stacktraces-truncating-in-logs 
For example: 
1) "When you see '...113 more', that means that the remaining lines of the 'caused by' exception are identical to the remaining lines from that point on of the parent exception." by Cowan 
2) "In a blog post I just described how to get more than just 'BatchUpdateException' " by MartinGrotzke 
 
As a last resource, since Appian uses log4j I can think about enabling some flags in some properties file, but this can give you more problems or complexity than a solution
