Hi @Sergii_Zelenskiy,

Can you provide a screenshot of the error and the input/output bundles? This will help better troubleshoot.

Hi @Sergii_Zelenskiy,

Please use the HTTP - Get a File to get a download of the PDF to use in later steps (Pictured)

You can plug in the S3 URL generated from PDF.co where the solid red rectangle is located.

Hope this helps!

Hi @Sergii_Zelenskiy,

Is there a reason you’re not using the Chatgpt module to hit openAI servers? I haven’t used the http module to run an opeAI api call.

That being said, can you provide the input bundle? It may be missing quotation marks, or a not properly assembled JSON.
