Describe the problem/error/question

Using the example faceless video script (EASY AI System Creates Faceless Videos on Auto Pilot!) I get an invalid URL error when the step for media upload to Blotato occurs.

What is the error message (if any)?

Invalid URL

## Information on your n8n setup
- **n8n version:** Unsure where to find this. Using the web app n8n in a trial basis. 
- **Database (default: SQLite):** SQLite?
- **n8n EXECUTIONS_PROCESS setting (default: own, main):** Unsure what this means
- **Running n8n via (Docker, npm, n8n cloud, desktop app):** n8n cloud
- **Operating system:** Mac OS

You can see all API requests, responses, and errors in your Blotato API Dashboard.

The error “Invalid URL” for this particular workflow is usually due to:

  • running out of AI credits so the video didn’t finish generating
  • not waiting long enough for the video to finish generating; longer scripts require a few more minutes to complete

I’m also in the process of updating these older workflow templates with the new blotato n8n node, which makes it 10x easier to create and publish content.
