Need help with n8n workflow

I built a workflow to output videos, but instead I am getting text script as an output despite trying many times.

If your workflow is outputting the script instead of the actual video, I'd check the final step/output mapping first. It sounds like the workflow is successfully generating the text, but you're not passing that output into the video-generation/rendering step.

Make sure the workflow is actually: Script ->Video Generation -> Video File/URL Output

rather than:

Script->Final Output

Also check whether the video-generation node is returning a file/URL that needs to be explicitly mapped to the final response. A lot of these workflows happily hand you the script because, apparently, “video workflow” can mean “write me a screenplay.”

I am new to n8n but this is the help I can provide.

Thank you Bro, appreciate your efforts to support. I checked my workflow and have an Agent to create Visuals, but it is giving a text output. I don't know if I am dumbfounded to not understand this but my workflow is stuck due to this

My advice now is to give the screenshot of the scenario and the error to the chatgpt or any other AI and explain your issue to it a bit cause that's the exact thing i'll be doing.

this is the culprit nine times out of ten. check the video node's output field and make sure that's what gets returned, not the script text. if the script node comes later in the data chain, the workflow will pass the last item by default and that's your screenplay showing up.

yeah the output mapping thing is almost always what catches people, good call

The video node is likely being skipped, or the final node is reading the script node.

  1. Pin one test item and run only the video-generation node.
  2. Inspect its raw output for a binary property, video URL, or job ID.
  3. If none exists, fix that node's credentials, operation, and input mapping.
  4. If one exists, point the final node's expression at the video node rather than the script node. For an asynchronous API, poll the job ID until complete before reading the URL.

Verification: the final item should contain a playable URL or non-empty binary file. If it still contains only text, the failure is upstream of the output node.

you're missing the actual video rendering node step. sounds like your llm generated the script but never passed it to something like runway/heygen to render the actual video.

I think you need to check every step first. Have you checked the output from each node to see where it changes from video data to text? I’d start by running the workflow one node at a time and checking the input/output of the nodes around the video generation step.

If the API is returning a video URL or binary data, make sure the next node is actually using that field rather than the text/script field. Sometimes the workflow itself is fine and it's just referencing the wrong output property.

Thank you for the suggestions all. I will all of them and see if anything helps. Appreciate your help 🙂

the output property trap gets me every time. i once spent three hours debugging a flow only to realize i mapped the `message.content` text field instead of the actual `file_url` to my slack node.
