When I try to fetch using GET I recieve an error 502 but when I fetch using POST i recieve the response.
Lambda:
const headers = {'Content-Type':'application/json'}
exports.handler = async function(event) {
return {
statusCode: 200,
headers: {
headers
},
body: JSON.stringify({"ok":"ok"})
}
};
Fetch:
fetch("https://n3bvznv385.execute-api.us-east-2.amazonaws.com/dev/juegos", {
method: 'GET',
headers: {
'Content-Type': 'application/json',
'Accept': 'application/json',
'authorizationToken' : '123',
}
}).then(response => response.json())
.catch(error => console.error('Error:', error))
.then(response => console.log(JSON.parse(response.body)));
API Gateway expects the following response format from your Lambda when you are using Proxy Integration:
{
"isBase64Encoded": true|false,
"statusCode": httpStatusCode,
"headers": { "headerName": "headerValue", ... },
"multiValueHeaders": { "headerName": ["headerValue", "headerValue2", ...], ... },
"body": "..."
}
You are, however, passing a nested object as headers as your code resolves to this:
headers: { {'Content-Type':'application/json'} }.
Try to include possible headers like this instead:
exports.handler = async function(event) {
return {
statusCode: 200,
headers: headers,
body: JSON.stringify({"ok":"ok"})
}
};
