How can I convert "google.cloud.documentai_v1.types.document" object to json

Question

I am using Google Cloud Document AI's Invoice Parser. API response is google.cloud.documentai_v1.types.Document object. I tried to write below approaches for converting it to JSON but nothing works:

• json.dumps() but it gives JSONDecodeError
• google.cloud.documentai_v1.Document.to_json()

Answer 1

You should be able to get the JSON with the to_json method you mentioned, but you have to pass the document you want to get as a JSON file, such as

google.cloud.documentai_v1.Document.to_json(my_document)

which will output the JSON file.
