Dear @amritsundarka
We understand your request, but we need a sample project where you implemented the Force Save scenario that failed. This way we will be able to check out entire scenario and figure out the situation. Unfortunately, we don’t have ready-to-go React.js sample with Force save feature for your reference, so we need a proper sample from your side to check out.

The provided earlier sample doesn’t contain Force Save scenario, so we cannot troubleshoot it.
Please provide us with proper sample or contact colleagues of mine to discuss possible options to speed up the process: Get dedicated support
