Got a function working locally, triggered when a file is dropped and now deploying to azure.

Function signature looks like this. Notice the binding expression.
This expression is attempting to pull a value from appsettings called “MyFolderPath”
Locally this works as expected. The path is container/folder_name
The setting is available in azure under Environment variables.
However, when I drop a new file in that path, the function is not triggered or invoked.
What can I check?

public async Task Run([BlobTrigger("%MyFolderPath%/{name}",Connection = "FuncStorage", Stream stream, string name)
