azure function app functions are not getting deployed.

I was trying to to deploy the application in azure on west europe with gpt 4o as the model for a PoC purpose.
For that I update the open AI bicep and main bicep and deployed the latest code. The code executed without any error.
But the deployed function app is showing run time version error and no functions are showing the in the function app. If you have any suggestions or solutions kindly let me know.
Thanks
