无法从亚马逊获取访问令牌

Question

I'm trying to add amazon sign in following "The Authorization CodeGrant" I get the code client side and send it to my node js express server but can't get the access token from amazon. I get 500 Internal Storage Error and:

x-amzn-errortype': 'InternalFailure:http://internal.amazon.com/coral/com.amazon.coral.service/'

My code:

async function getAmazonAccessTokenFromCode(code) {
    try {
        const { data } = await axios({
            url: 'https://api.amazon.com/auth/o2/token',
            method: 'POST',
            headers: {
                "Content-type": "application/x-www-form-urlencoded"
            },
            params: {
                grant_type: "authorization_code",
                code,
                client_id: "my_client_id",
                client_secret: "my_client_secret",
                redirect_uri: 'http://localhost:3000/amazon-auth',
            }
        })
        console.log("data", data)
        return data.access_token
    } catch (err) {
        console.log("err", err)
        return null
    }
}

Answer 1

I made it work by replacing "params" with "data" in the axios fetch request.

Answer 2

Also, if it doesn't work try to use application/json in content type. It worked for me.
