Excel Online (Business) 'Add a row into a table' action failing *File Identifier code while other Excel Online (Business) actions are working smoothly.

[Reylin]

I am using the following Excel Online (Business) actions: Get worksheets, Create worksheet, Create table, List rows present in a table, Get a row, Update a row. 
All of these actions work with dynamic content code inside the *File identifier field. 

The action "Add a row into a table" action is giving me an error and causing the flow to fail. 

When I put the "Identifier" dynamic content into the field, or when I compose the identifier, or when I put the file path, etc... all of it fails with this error code: 

{
  "status": 400,
  "message": "The expression \"[REDACTED]" is not valid.\r\nclientRequestId: [REDACTED]",
  "error": {
    "message": "The expression \"[REDACTED]" is not valid."
  },
  "source": "excelonline-eus.azconn-eus.p.azurewebsites.net"
}

However, when I manually choose a file by clicking on the folder icon (as in the picture below), the flow suddenly works. 

I need the File identifier field to work dynamically just like every other Excel actions I am using. 
Why is this action in particular failing; why is it different than the rest when it looks like it is setup the same? 
The others are working as intended. 
Someone please help! ❤️

Hi @Reylin ,

I have made a test on my side and the issue is confirmed on my side.

I'm afraid that the identifier dynamic content is not supported in the "List rows present in a table" action in Microsoft flow currently, I suggest that you submit an idea to flow ideas forum if you would like the function to be supported in Microsoft flow:
