AEM FORM Data model - Exception - datasource panel not opening

[nj2]

Hi All, 

We are experiencing an error when trying to open Form Data Model, and which is preventing data source panel from opening up. 

Has anyone encountered a similar issue or can provide any guidance or pointers to resolve this.

Are you still getting this issue?

Are there any particular error msgs in the logs while fetching the Datasources? What is the data source service type that you're setting up?

Hi Pulkit, 

Yes, issue still persists. and I do not see any errors in the logs. Issue is not related to the datasource, it appears that issue is arising due to custom multifield wrapper.
