@Kelvin Daniel Thank you so much! I just tried that but it's not working. I used AI to try and help me and tried all of the steps that it gave me, still not working.

@Kelvin Daniel I had different issues while trying to fix the problem. I tried to add myself as a test user but it said: " Ineligible accounts not added The following email addresses are either not associated with a Google Account or the account is not eligible for designation as a test user: ", but it is my correct Google account and the credential was successful. When I manually added the scopes and recreated the credentials, the only issue was that the spaces bar did not change. I also deleted the entire workflow and started over again, still nothing changed. I deleted the document on my Google Drive and created a new one as a PDF and as a Google Doc, still did not work. AI told me that it could be the URL, so it gave me another one to try, still did not work. Sometimes an error would also pop up when I was trying different options, so I would delete the credentials and change stuff around again until I had the connection working again. I'm not sure if there's anything to do, but my only credentials are the Google Drive and n8n free OpenAI API credits. I will also send you some of what the AI agent told me. I spent the whole day trying to figure it out but I couldn't. I really appreciate your help!!

@Quoc Anh Vu I used testmyprompt.com built the whole model there, then created an API key, then conected my final model to manychat. I was following another course here in skool. The first software is 75,00 but you can get a discount for the first 3 months (15,00) and just try it out, then I loaded $5,00 to my API account, and manychat gives you a 14 days free trial. So to make it and run, I spent 20 dollars, but It's a lot easier than n8n, and I finished on the same day. I can also send the course, I will make another comment because I need 4 likes to be able to ask a question lol

@Quoc Anh Vu Anytime!😁 This is the link for the course: https://www.skool.com/ai-automation-a-z-7282/about?ref=689203b4fef444db9970eabac84d4d3f AI automation (A-Z) I recently started creating models, but I personally did not had issues with messages yet, the only part that gave me a bit of trouble was developing the prompt, but what problems in specific are you referring to? maybe I could help. If you want I can also share my model, it's on my friend facebook page, and you could try it out.

I am just now getting started on N8N, but I created my first one using other softwares, which for me was a lot easier, but again, I am just starting my journey with AI. The prompting was a little complicated but it works well! I published on my friends facebook page and it's a good costumer service agent.
