[BUG] Azure Function PromptFlow Issue

[stalinjose1234]

We use an Azure Function App to run PromptFlow. However, our function app has suddenly stopped detecting any functions, displaying zero functions in the portal. Additionally, we are encountering the following error.

To troubleshoot, we tested a simple Hello World application with PromptFlow as a dependency, but the issue persists.

Result: Failure
Exception: Exception: Promptflow may not installed correctly. If you are upgrading from 'promptflow<1.8.0' to 'promptflow>=1.8.0', please run 'pip uninstall -y promptflow promptflow-core promptflow-devkit promptflow-azure', then 'pip install promptflow>=1.8.0'.
