Uncaught (in promise) SyntaxError: Unexpected token < in JSON at position 0 #1
Description
Hi, When I click submit I got this error,how I can fix it? I have write the same thing has your....
I have added isCaptchaValid(true); for my custom script
And on my side I run on the port 3000 not 4000
const submitData = token => {
// call a backend API to verify reCAPTCHA response
fetch('http://localhost:3000/verify', {
method: 'POST',
headers: {
"Content-Type": "application/json"
},
body: JSON.stringify({
"name": inputName,
"inputEmail": inputEmail,
"g-recaptcha-response": token
})
}).then(res => res.json()).then(res => {
isCaptchaValid(true);
setLoading(false);
setResponse(res);
});
}
This is the error:
