Hello Karol,

Moca is a custom data adapter. Can you please list all the steps that you followed for the Moca data source setup? Was this working before? is this the first time that you are trying to set up the connection? Are you using the community version of Jaspersoft or any commercial? When you get a chance, Please share all the details and we can guide you in the right direction.

I was also facing the same issue. The error is due to a missing or improperly defined method

supportsGetFieldsOperation in the

com.jda.reporting.jss.plugin.JdaMocaConnectionDescriptor class.

This indicates a compatibility issue between the JDA MOCA Mulesoft Connection adapter and the version of Jaspersoft Studio or JasperReports you are using. Ensure compatibility, update libraries, and check method implementation. Refer to their documentation or contact  support .

Hope it helps you.
