Update 0924:

You should do the append action first, then do the flush action:

step 1:

append action, make sure the json length is correct. Then in postman:

In headers:

In body, input the json:

step 2:

Then do the flush action in postman:

The error message gives a tip but not detailed. Actually, you're missing the required header: x-ms-date .

So please add x-ms-date and it's value(UTC/GMT format) in the request header like below:

x-ms-date: Mon, 23 Sep 2019 05:53:53 GMT

For how to generate the value for x-ms-date, using power shell as example:

In power shell, using this line of code: [System.DateTime]::UtcNow.ToString("R")
