Translate curl request to axios request for AWS lambda function - node.js

Question

I'm trying to translate a curl request to an axios request as such:
Here is the curl request format:
curl -s -X POST \
-d '{"version": "12ac28616dba364cc9f1e30c610c6efd62dbe9b9c7d1d03ea", "input": {"prompt": "sunset over a lake in the mountains"}' \
-H "Authorization: Token 123123123123123123" \
-H 'Content-Type: application/json' \
https://api.replicate.com/v1/predictions
And here is how I translated it to an axios request:
try {
const response = await axios.post(
"https://api.replicate.com/v1/predictions",
'{"version": "12ac28616dba364cc9f1e30c610c6efd62dbe9b9c7d1d03ea", "input": {"prompt": "sunset over a lake in the mountains"}',
{
headers: {
Authorization: "Token 123123123123123123",
"Content-Type": "application/json",
},
}
);
console.log("RESPONSE ----->", response);
} catch (err) {
console.info("ERROR---->", err);
}
However, I keep receiving the following error:
ERROR----> [AxiosError: Request failed with status code 400] {
code: 'ERR_BAD_REQUEST'
Is the code formatted properly?

Answer 1

You are forgetting the Token part in the Authorization header:
Authorization: "123123123123123123"
If you look on the response from your axios call you will see this:
data: { detail: 'Authentication credentials were not provided.' }
So just update your code and add the Token:
Authorization: "Token 123123123123123123"
I also think you might have problem with you actual data, try sending it like this instead:
const response = await axios.post(
"https://api.replicate.com/v1/predictions",
{
version: "12ac28616dba364cc9f1e30c610c6efd62dbe9b9c7d1d03ea",
input: {
prompt: "sunset over a lake in the mountains"
}
},
{
headers: {
Authorization: "Token 123123123123123123",
"Content-Type": "application/json",
},
}
);
or serialize the data before you send it:
const data = JSON.stringify({
version: "12ac28616dba364cc9f1e30c610c6efd62dbe9b9c7d1d03ea",
input: {
prompt: "sunset over a lake in the mountains"
}
});
const response = await axios.post(
"https://api.replicate.com/v1/predictions", data,
{
headers: {
Authorization: "Token 123123123123123123",
"Content-Type": "application/json",
},
}
);
As you can see in your error message the data is getting escaped, so this is probably the problem:
data: '"{\\"version\\": \\"2e3975b1692cd6aecac28616dba364cc9f1e30c610c6efd62dbe9b9c7d1d03ea\\", \\"input\\": {\\"prompt\\": \\"sunset over a lake in the mountains\\"}"'
