Issue

When using the Mendix Platform SDK to create a working copy from a Git-based app, the operation fails with the following error:

RS400 - Please provide valid input to execute this request. An error occurred while reading the model file.

Environment

Studio Pro v11.3.0

Cause

A compatibility issue was introduced with Mendix 11.3 Git-based apps that caused the createTemporaryWorkingCopy call in the Platform SDK to fail when reading the model file.

Solution / Workaround

To resolve the error when using the Platform SDK with a Git-based Mendix app, upgrade the app to Studio Pro v11.5.0 or newer.
