Message Too Large to Process

I am receiving this error at the end of my process. The process completes all actions, including sending an email, but then this error pops up at the end.

I understand this is because the maxMessageSizeInMegabytes parameter has a default of 10 MB and that it can be changed in the config file. I have tried both paths in this link Message too large to process but I can’t find a Config file that contains that parameter.

Has anyone been able to solve this issue or find the config file? Thank you

I found information that:

The maxReceivedMessageSize was no longer used since 2019.4.

Ok thanks. Any other way to fix this then? Or do I have to change my entire process?

Did you check topic which I attached ?
Someone found workaround. Maybe you will try ?
