My Application (WEBAPI with Crystal Reports in Visual Studio 2019) runs fine in my local machine. However, when i deploy it to the test server. I am getting the below error when i run an API in the test environment. Test server has SAP Crystal Reports Runtime Engine 32 Bit Installed.

Error Details:
