Why do I get 404: component not found error when calling a function from MPS?

I am using MATLAB Production Server using Microsoft Azure. I create the deployable archive MATLAB function using productionServerCompiler. I then try to call the function by using POST and GET. When I use GET, I am receiving a 404 error stating that the component was not found. I looked up this error message using this MathWorks Documentation page:
https://www.mathworks.com/help/mps/restfuljson/troubleshooting-restful-api-errors.html?s_tid=srchtitle
This states that this error message is appearing because the CTF archive was not found. I made sure that the deployable archive (CTF) was located in the auto_deploy folder of the running server instance as mentioned here:

I am compiling the archive using MATLAB R2020b. Why is the archive not being found, and how can I resolve this issue?

Even if the CTF archive is located in the correct location, it will not be able to be properly read if the version of MATLAB Runtime used by MATLAB Production Server does not match the version that was used to compile the CTF archive. To resolve this issue, please be sure that these two MATLAB Runtime versions are the same.
