Applepay merchant validation failing with error request failed with status code 417

I am implementing apple pay and the merchant validation is failing with error (error request failed with status code 417). I am using react js in the frontend and node js in backend, this is my code

const httpsAgent = new https.Agent({ rejectUnauthorized: false, cert: fs.readFileSync( path.join(__dirname, "../../../certificates/merchant_id_prod.pem") ), key: fs.readFileSync( path.join(__dirname, "../../../certificates/merchant_id_prod.key") ), }); const data = { merchantIdentifier: "merchantId", displayName: "Check", initiative: "web", initiativeContext: "domain.com", }; const response = await axios.post(validationURL, data, { httpsAgent });
