Spring boot azure function : Http Trigger : This function was programmatically called via the host APIs return 500 error

Question

I am trying to create a spring boot azure function using the following guide

https://github.com/eggboy/springcloud-azurefunction/tree/springboot3

https://medium.com/microsoftazure/create-azure-function-with-spring-cloud-function-ab150216d2bd

I was able to successfully build and run the azure function on local.

but when I try to deploy and trigger the http endpoint, I am getting HTTP 500 . Could someone help understand what is going wrong here.

Although in logs it says 200 return, on browser and postman it is getting HTPT 500

https://xxx/api/getUserFunction?userId=abc

Error seen from browser

I am expecting successful return HTTP 200 response by the azure http trigger via both browser and postman, but both fails to with 500 error. But on local it works and return the expected result with HTTP 200
