Weird. Any info about the error in log file?
Nope
Hi, I found something similar https://community.appian.com/discussions/f/user-interface/18738/an-error-has-occurred-cannot-set-property-muted-of-null
What are we looking at? Any details? Code snippets?
I am also seeing this issue in my application, it is almost impossible to take the screen shot, just comes up for about a second. For the application I am working with, this pink screen comes-up when the interface tries to use the smart service, especially while trying to write to the database.
Upon a little research, one of the solution would be to check your interface's performance and follow the Appian best practices to improve it. As your interface might be doing some unnecessary heavy lifting. Weirdly there aren't any logs to fully understand this issue.
Also, and I am still trying to figure this and might be outside of our scope of working with Appian, but maybe due to network traffic. As I have even observed scenarios where the interface may throw this error today and might not tomorrow.
Looks like a problem with either your CDT's field or Map/Dictionary's field which cannot be read by Appian. Please attach some code snippets or try searching this "getin" in your code. That should be creating this problem!
Was your environment recently upgraded? We are also seeing the same error. Not sure if this is related to upgrade from 22.3 to 22.4.
Might be helpful to see the code but this thread could also provide some useful hints. community.appian.com/.../an-error-has-occurred-cannot-set-property-muted-of-null
