OEM, Config Extension: Where do I change the change the allowable size?

JVal

Error message: "Config Extension returned data size: 11308730 bytes exceeds maximum allowable size: 5242880 bytes. Fix the Config Extension to return a smaller content size or change the allowable size ."

version 13.4.0.9

I couldn't find anything about where to configure this value in the docs or online. Any ideas on where I can find it?

Thanks
