Text Input Field is the name of the parameter.
This is used sometimes for values that probably have a greater size.

In your case: replace {{ $json.output }} with output

[Wouter_Nigrini]

I think you’re supposed to only provide the field’s actual name and not the value or content of the field. Set the property to “Fixed” and the name of the variable, which is “output”

[Wouter_Nigrini]

Yes, did this work?

[Anthony_Chet]

Thank you so much for your help. Do you think you can help me with one more part of this problem? after I convert it to binary data file its not allowing me to upload it to OneDrive

[Anthony_Chet]

Thanks for your help!

[Wouter_Nigrini]

Can you share your workflow in a code block? From the screenshot it should work. I did however notice that you’re trying to upload a text file as a docx. Ideally you want to pull the filename out of the binary properties and use that instead for consistency.

I Solved it thanks for your help!
