Problem with Incident extended property

Eruann

Hi!

Recently we have installed the community web portal version 9.3.4 on our production enviroment.

i have a problem with an extended property of an Incident, it's a string property internaly named "WorkItem" . The problem is that when i Fill that property the users (Analyst and End-User likewise) get this error:

If i clean the property, everyone can acces the incident without problems. Sadly we use that property so it's not an option.

Can you help me?

Cachebuilder.log shows no error.

Webconsole.log throws this:

2019-08-23 18:44:21,369, ERROR [ 25]: Incident / Edit

One more thing,

We have another String field internally called "Closed_Description" , we dont have any problem with that field. Only when an analyst fills the "workitem" field we get the error.

thanks!
