Converting PDF to Plain Text Using Adobe Services API (without PDF.co)

Hello,

I want to convert a PDF into a text without using PDF.co. In my search for an alternative solution, I came across the Adobe Services API
Scenario:

Upload the PDF from Google Drive.
Use the HTTP module to generate an access token.
Upload the PDF to Adobe Cloud: After uploading, I receive an assetID and an uploadUri.
Extract the text from the uploaded PDF: Using the Adobe Services API, I extract the text from the uploaded PDF.

I’ve tested this flow in Postman, and everything works fine up until the text extraction step. However, I receive an error with the following details:

Error: 404 Not Found

{"error":{"code":"NOT_FOUND","message":"Asset Not Found."}}

It seems the document cannot be found in Adobe Cloud, even though I’m using the assetID and uploadUri I received during the upload step.

I used the documentation of Adobe Services API.
Could somebody help me?

Thank you.
