Problem:
I have a node.js server running on localhost on port 3000. When I do a POST request in an app function I get an error. If I do the same request to remote url it works fine.
Error I got:
console.error
response failed because: TypeError: fetch failed
at fetch (C:\Users\markus.hobisch\IdeaProjects\dynatrace-cpa\node_modules\undici\index.js:105:13)

}
}
I added a screenshot with the error I got in debug UI as well.
I just made a simple post request to localhost and remote host. To produce the error you can use the code below:
const urlLocalhost = 'http://localhost:3000/api/cloudwatch-logs-simulator';
const data = {
logStreamName: 'name',
startTime: 1675926120000,
endTime: 1675926300000,
nextToken: 'f/90/s',
limit: 100,
};
const urlRemote = 'https://jsonplaceholder.typicode.com/posts';
let response: Response;
try {
response = await makePostRequest(urlLocalhost, data);
} catch (error) {
console.error('response failed because: ', error);
return;
}
const json = (await response.json()) as Promise<CollectCloudwatchLogsResponse>;
return Promise.resolve(json);
}
const makePostRequest = async (url: string, data: any): Promise<Response> => {
const response = await fetch(url, {
method: 'POST',
headers: {
'Content-Type': 'application/json',
},
body: JSON.stringify(data),
});
if (!response.ok) {
throw new Error(`HTTP error! Status: ${response.status}`);
}
return response;
};
