Hi,

I'm running into some CORS errors when sending a GET request to my lambda service's function URL. I've tested this request with Postman and it's returning 200 ok. But when I try the same request in the browser it throws a CORS error.

Here's my init code:

export const axios = require('axios').default
import { aws4Interceptor } from 'aws4-axios'

const interceptor = aws4Interceptor(
    {
        region: 'us-east-1',
        service: 'lambda',
    },
    {
        accessKeyId: 'ACCESS-ID',
        secretAccessKey: 'SECRET-KEY',
    }
)
axios.interceptors.request.use(interceptor)

And then it's just a simple axios.get() request to the AWS-LAMBDA-FUNCTION-URL.

Am I missing something?

Thanks!
