Im getting the following error when I try to make post request to my own typeorm API using axios:
TypeError: Converting circular structure to JSON
--> starting at object with constructor 'ClientRequest'

I have tried to use some libraries to fix the circular structure JSON and parse it but both failed:
const safeStringify = require('json-stringify-safe');
const CircularJSON = require('circular-json');
None of the entities's relations have cascade option added.
await axios.post(apiName+'/object', data, { headers: { Authorization: res.req.headers.authorization } }).then(response => { res.send(response); });
Data example with the object I want to persist in my database:

If I try to post this JSON via Postman It works propperly. Buy not by code, maybe due the circular problem with the Entities

I think
res.sendmight be expecting something other than an entire response object. – backtick Commented Dec 26, 2020 at 18:05 - 2 @backtick You were right, I was supposed to do res.send(response.data) not the whole response object. Such a noob fail hahaha thank you bro!! – Miguelo Commented Dec 26, 2020 at 18:11

Reset to default 5As @backtick said, I was supposed to do res.send(response.data) not the whole response object. Thank you
TypeError: JSON circular structure starting from the object
Delete that property from the object you want to return that caused this error or loop
Example:
Delete object.property in your case Delete object.socket
