Http node Error : JSON response

Questions
1

Hi there,

It seems i’ve the same issue as described here : HTTP node - Response Format JSON ➝ response with empty body ➝ no output - #5 by antitalent

When an HTTP node get an Error, the error message is unusable, it is not the error message my API is sending. It’s come with a lot of “axios things” and i cant parse message error.

"error": 
{
"message": 
"400 - "{\"errorCode\":400,\"message\":\"WRONG_SEALINE\",\"details\":[\"Invalid carrier alpha code (SCAC) specified\"],\"time\":\"2024-02-22T15:12:24.286266028Z\"}"",
"name": 
"AxiosError",

Is there a way to just get the error my API is sending instead of all this axios syntax ?

I use the “continue (using error output)” option because i need to send the error to my front end (webhook/respond to webhook dynamics)

Thanks :slight_smile:

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:

Hey @dubarseo,

The error from the API is in the message so in theory you could use error.message and remove the status code then convert the rest to json.

Hey @dubarseo,

Quickest I can think of would be a replace or slice to remove the first part then use the JSON.parse() javascript method.
