Bug when using a secrets.json local file with BlobTrigger

[neothoms]

When using a connectionString for the BlobTrigger in secrets.json local file there is an issue when the event is triggered.

The Function correctly connects to the events of my blobstorage.
When I create a file to the container, I can see that the trigger is invoked on the func console but the Function is not correctly called since the ConnectionString is not found.

Now if I set the connection string in the local.settings.json instead of the secrets.json, the function will work without any issue.

There is something that prevents the triggered function to access the secrets.json file.

Reproduction of the issue.
Create an azure function in visual studio.
Add a BlobTrigger function to that function using the wizard to create the connection string to a storage account

This will create the function and add a secrets.json file in your user folder %APPDATA%\Microsoft\UserSecrets\

Execute the function and add file to the container. This will recreate the issue

Thanks fore reporting please share the all repro step will check and update you

[neothoms]

All the repro steps :

Create a new project Azure Function .net in Visual Studio with no methods

Add a function to the VS project
Create a function Blob Trigger as the screenshot shows it with connection string.

Choose to connect to an azure storage directly

Select an existing azure storage from one of your subscriptions

Choose the following config

Visual studio should store the connection string on a secrets.json file in your Local user folder and add some nugget packages.

Then you should reproduce the bug

ok Thanks for update.

[bhagyshricompany]

can you try again the same?if not open the issue on azure portal.

No reply hence closing if have issue pls open .Thanks
