Use-chatgpt-to-write-long-blog-posts-on-wordpress-1500-words Model: doesn't work

I tested the tutorial in this article Use ChatGPT to automate writing long blog posts on WordPress (1,500+ words) - Activepieces, but it does not work.

The Code module gives an error:

SyntaxError: Unexpected token O in JSON at position 0
at JSON.parse ()
at Object.code (/root/codes/step_4/index.js:5:22)
at Object. (webpack://activepieces/engine/src/lib/executors/code-executer.ts:9:32)
at ()
at fulfilled (webpack://activepieces/node_modules/tslib/tslib.es6.mjs:118:41)

Unfortunately, as a new user I cannot attach screenshots.

Can you help me, please?
