Unable to import module 'lambda_function': No module named 'aws_xray

I am trying to implement this AWS Lambda Rest API Handler in my lambda code to handle proper response code. For this I needed to repackage the library aws_lambda_powertools and add as a layer in lambda function.

All the import related to this lib below are working.

from aws_lambda_powertools import Logger, Tracer
from aws_lambda_powertools.event_handler import APIGatewayRestResolver
from aws_lambda_powertools.logging import correlation_paths
from aws_lambda_powertools.utilities.typing import LambdaContext

But When I am creating object of above Tracer class below its giving error(Rest two commented object logger and app are working fine.

tracer = Tracer()
# logger = Logger()
# app = APIGatewayRestResolver()

Error I am getting while declaring tracer object is below:

Response
{
  "errorMessage": "Unable to import module 'lambda_function': No module named 'aws_xray_sdk'",
  "errorType": "Runtime.ImportModuleError",
  "stackTrace": []
}

I tried to install pip install aws_xray_sdk and repackaged it and re-added to layer still its giving the same error.

Can anyone help me with this? I am new to lambda. Thanks in advance.
