Unable to get query parameters

[kaissun]

Hello team,

I am using this example to have my own sagemaker model:
https://github.com/aws/amazon-sagemaker-examples/tree/main/advanced_functionality/scikit_bring_your_own
It is using the proxy server nginx. It is working fine when I build and test locally using the docker image with entrypoint serve file script.
But, in the seconde test case, I deployed the sagemaker model, and I tried to call the invocation method using the SDK library for JAVA and trying to call with query parameters and even with a custom header, I cannot read them as I have to use them as parameters.

I tried to play with nginx config in this file but no success:
https://github.com/aws/amazon-sagemaker-examples/blob/main/advanced_functionality/scikit_bring_your_own/container/decision_trees/nginx.conf

Do you have any idea how to pass the query parameters and read them in the perdictor.py file through invocations post request?
Thanks in adance.
