Google Sheets row append call always return error on "value"

[andrewkyiv2000]

I have complexity to make Google Sheets row append call via integration described here :

The problem always appear on “value” field. If I setup Input Arguments as:
Input Argument Name: values
Input Argument Value: [“value”]
I receive error: “expected string, received array”

If I make the value as string: {“value”} or any other options: {{value}}
I receive: “Error: values must be a valid JSON array”

What is the correct format to write the value? And how is possible to place here the output from the agent flow (i..e. real data I receive from previous agents like {{agentAgentflow_X}})?

My input argument settings

Thanks for your help!
