Azure Storage Queue and Managed Identity

I am having trouble connecting my Logic App to an Azure Storage Queue. I followed MS guide for setting it up: https://docs.microsoft.com/en-us/azure/logic-apps/create-managed-service-identity

Here is my test Logic App to post something to my queue:

When my Logic App is triggered I get an error:

enter image description here

AuthenticationFailed.Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

Why is it requiring me to include an Authorization Header, when I stated that I want to use Managed Identity? As far as I have read on MS docs, the Queues do support Managed Identities.

Do you have any other concerns? - Jim Xu
I saw that the in my screenshots here I didn't have the "/messages" in my URL. So it should be saqueuespoc.queue.core.windows.net/myqueue01/messages. Without '/messages' in the URL in just gives HTTP 405 Unsupported Verb error. So the main solution for HTTP 403 error with using Managed Identity is to include "x-ms-version" in the request like you stated below. - Oliver Nilsen

According to my test, if we want to call Azure queue storage rest API with Azure AD auth, we need to specify x-ms-version in the request header and its value should be 2017-11-09 or higher. Otherwise, we will get error 403. For more details, please refer to the document and the document

My test is as below 1. If I do not specify x-ms-version, I get the error

  1. If I specify x-ms-version, it is ok

My request Headers in HTTP action

 "Content-Type": "application/xml",
  "x-ms-date": "@{utcNow('R')}",
  "x-ms-version": "2019-07-07"

This worked for me: Put/Post JSON message to Azure Storage Queue via Logic App

Final result in Logic App designer enter image description here
