Integration Object - Unable to process request body

Hi All,

I am facing issue in integration (soap request) while uploading large file size document.

Error: Unable to process request body - The request body was greater than 5 MB and could not be processed.

I tried with content type - text/xml, application/xml ,custom: application/soap+xml; 

Third party system accepts only content type - text/xml and application/soap+xml


I have also referred article - Integration Object - Appian 22.4  

Can someone please help me on this?

Thanks!
