Blank Page when the flow action aails


I am using Pega 7.3.1.

During the execution of my Case, I am running a Flow Action. On the Post Data Transform, I am setting an error in pyWorkPage to simulate an error. Generally, Pega will reload assignment that failed and show the DisplayError page. Whoever, on this particular case, it is showing a blank Page instead and all navigation buttons are lock (they just don't do anything).

I have checked the logs and the only error I can see is one thrown by HTML:ReloadSection:

The reference getMessagesAll())%> is not valid.  Reason: unexpected character ')' at position 15, expected subscript (wildcards not allowed)

Does anyone have a clue about what could be happening here ?

Thanks in advance,

I am getting a wrong behaviour when a flow action gets an error on the page.

Based on the error, the reference getMessagesAll())%> is not valid. What is the ")%>" after getMessagesAll()?

Can you show us how you set an error in pyWorkPage to simulate an error on your post Data Transform?
