We have migrate from 16 to 19.  
After the upgrade I wanted to take a look at the SAML Identity Provider mapper settings.  
No matter which mapper I click on, I get the following error message:

**undefined" is not valid JSON**.

All other settings are displayed correctly.

Is a bug?

Has anyone had similar experiences?
