axios POST get 400 - axios

Question

This is driving me crazy!
Exactly the same POST request works fine in Insomina per screenshot below:
The only header Insomina has is: Content-Type: application/json.
Now, the same request in code (I even copied the code generated from Insomnia for axios) via axios in Typescript:
const saveReqConfig: AxiosRequestConfig = {
method: 'POST',
url: 'THE SAME URL USED IN Insomina',
timeout: 3000,
data: {
name: `TestName`,
uri: `TestURI`,
statusCode: '200',
simulatedLatency: '0',
contentType: "application/json",
tags: '',
response: 'testing...',
type: 'VA',
},
headers: {
'Content-Type': 'application/json',
}
}
const normalAxios = axios.create();
const test = await normalAxios.request(saveReqConfig);
Don't understand why I am getting AxiosError: Request failed with status code 400 from code but the same request works fine in Insomina.

I think you did not set the headers correctly or you may not have setup the .create() properly.
Something like this:
const instance = axios.create({
url: '/post',
baseURL: 'https://httpbin.org',
method: 'POST',
timeout: 1000,
headers: {
Content-Type: 'application/json' // <- set your headers
}
});
let res = await instance.request({ // <- pass the data here
data: { // This should be whatever you want to post to this url. I just copied what you had.
name: `TestName`,
uri: `TestURI`,
statusCode: '200',
simulatedLatency: '0',
tags: '',
response: 'testing...',
type: 'VA',
}
});
Are you sure you need to use the .create() factory? The normal post like this might suite your needs better?
const data= { title: 'Axios POST Request Example' };
const headers = {
Content-Type: 'application/json'
};
axios.post('url', data, { headers }).then(response => console.log(response.data.title);

Posting here in case it helps someone.
It turned out that I couldn't post the request programmatically is because of lack of a TLS certificate. I didn't know that Insomnia has the option to disable the TLS and that's why it works in Insomnia.
To disable TLS (Do NOT do this in production!) from node with axios, create an instance of axios with a https agent setting rejectedUnauthorized to false e.g.
const instance = axios.create({
httpsAgent: new https.Agent({
rejectedUnauthorized: false
})
});
Also, set the environment variable as:
process.env.NODE_TLS_REJECT_UNAUTHORIZED = '0';
