My first question using the most basic workflow

Questions
1

Building my very first test workflow, I based my workflow setting from @ giulioandreini in Parsing Json items, and practically nothing more is added to my workflow.

I set the workflow to accept multiple HTTP methods (GET and POST). Using production URL and web browser and GET, I get The URL of the Google search query for the term " " is:, which is expected.

Now, using the same production URL, using Postman and POST, I get “message”: “Error in workflow”.

Any idea why the difference?

  • n8n version 1.72.1
  • PostgreSQL 16
  • EXECUTIONS_PROCESS: default (no idea what it is yet)
  • Docker
  • Debian 12

It looks like your topic is missing some important information. Could you provide the following if applicable.

  • n8n version:
  • Database (default: SQLite):
  • n8n EXECUTIONS_PROCESS setting (default: own, main):
  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

Tip for sharing information

Pasting your n8n workflow

Ensure to copy your n8n workflow and paste it in the code block, that is in between the pairs of triple backticks, which also could be achieved by clicking </> (preformatted text) in the editor and pasting in your workflow.

```
<your workflow>
```

That implies to any JSON output you would like to share with us.

Make sure that you have removed any sensitive information from your workflow and include dummy or pinned data with it!

The workflow you pointed out to does not use the Webhook node. How do you try to use Postman in that case if nothing listens to incoming requests?

Could you share the actual workflow you have created as well as the error produced by the workflow (and in which node) when it responds to your HTTP request from Postman?

Thank you for helping! Much appreciated.

Here is the workflow:

PS: selecting All, copy and paste just paste the colored background but won’t paste the actual nodes…

The JSON n8n should receive has this (not showing the whole JSON, but the required bit). I want to match the id and extract value:

{
  "id": "67680139fbe2a0001131dd33",
  "formId": "JgZ7vTvN",
  "formName": "Raldmoyer AD-100 warranty registration",
  "answers": [
    {
      "id": "yRFiBOrwe7uf",
      "title": "您的手機號碼",
      "kind": "short_text",
      "value": "nmnmnnm"
    },
    {
      "id": "nxD0fOTscX12",
      "title": "您的機身號碼",
      "kind": "short_text",
      "value": "787878"
    }
  ],
  "hiddenFields": []
}
