Configuration: Please provide the following

• Azure OpenAI model name and version (e.g. 'gpt-35-turbo-16k, version 0613'): gpt-4o
• Is chat history enabled?: yes
• Are you using data? If so, what data source? (e.g. Azure AI Search, Azure CosmosDB Mongo vCore, etc): no
• Verify the startup command and runtime configuration by showing the output of the following az CLI command:

az webapp show --name <app name> --resource-group <resource group name> --query "{startupCommand: siteConfig.appCommandLine, runtime: siteConfig.linuxFxVersion}"

I do not know how to do this.

Logs
I do not know how to do this.

1. If the application deployment is failing, please share the deployment logs using the following az CLI command:

az webapp log deployment show --name <app name> --resource-group <rg name>

2. If the application is crashing after deployment, please share the application logs using the following az CLI command:

az webapp log tail --name <app name> --resource-group <resource group name>

Additional context
Add any other context about the problem here.
It should be fairly straight forward - I do not know why it is not working.

"I am experiencing the same issue. In some cases, the deployment is successful, but when it fails, I get the error message 'ModuleNotFoundError: No module named 'app', resulting in a failed deployment."

Experiencing same issue, have you managed to get it resolved ?

[saschadoemer]

@mgroupservice it was the redeployment which was successful for me. It looks like a glitch during the deployment.

Encountering the same issue causing inability to browse the web.

It might sound a silly workaround, but before deploying it to production, I removed frontend folder from source code and it got deployed and worked successfully. Not once but many times, tried this and surprisingly it works.
