Python and TERR service - Error when using script that uploads files larger than 100MB

When using a TERR or Python script that upload files you might run into the following error when running it on the server (but it works when running it locally):

Could not execute function call 'DatafunctionName'
 Unable to write data to the transport connection: An established connection was aborted by the software in your host machine.

The error occurs when the uploaded files are larger than 100MB.

There is a size limit that can be increased using the following settings for the TERR and Python services:

spring.servlet.multipart.max-file-size

spring.servlet.multipart.max-request-size

Please see the following documentation:
