Describe the problem/error/question

I’m using the IMAP trigger and retrieve data there e.g.:

"textPlain": "Hello, \n \n \n \nKind Regards\nOur website: https://domain",

Then, I want to POST this data with an HTTP request into an API.

"name": "{{ $('Email Trigger (IMAP)').item.json.subject }}",
"description": "asdf",

works fine.

"name": "{{ $('Email Trigger (IMAP)').item.json.subject }}",
"description": "{{ $('Email Trigger (IMAP)').item.json.textPlain }}",

throws an error:

JSON parameter needs to be valid JSON

I’ve tried this:

"description": "JSON.stringify({{ $('Email Trigger (IMAP)').item.json.textPlain }})",

But it throws an error as well.

Is there a good solution to make that future proof?
The plain text and the HTML mail?

What is the error message (if any)?

JSON parameter needs to be valid JSON

I didn’t have to do anything special. Simply this:

works fine. Could you share your config for the HTTP request?

You need to place JSON.stringify() within the curly brackets, or it won’t be evaluated:

"description": "{{ JSON.stringify($('Email Trigger (IMAP)').item.json.textPlain)  }}",

Thanks, that was it.
(plus the quotation marks which come from the IMAP node already)
