ODBC Driver Installation in Function App Dockerfile Causes Missing Function After Deployment

[Pavan-Microsoft]

We successfully added a step in the web app's Dockerfile to install the ODBC driver, and the application worked as expected. However, when applying the same step to the function app Dockerfile, the deployment completed without errors, but the function does not appear under the function app in Azure after deployment.

Steps to Reproduce:
Add a step to install the ODBC driver in the function app's Dockerfile.
Build and deploy the function app using the updated Dockerfile.
Verify the deployment status in Azure.
Check for the function under the function app in Azure.

Observed Behavior:
The function does not show up in the function app after deployment.

Expected Behavior:
The function should be visible and functional in the Azure function app after deployment, similar to the web app implementation.

Additional Details:
The same Dockerfile step works in the web app.
Deployment logs show no errors.
Using Azure Functions with a custom container.
