javascript - Recaptcha V3 error incorrect-captcha-sol randomly - Stack Overflow

I'm getting incorrect-captcha-sol error code sometime while using Google reCAPTCHA server side verification api.

I have integrated google recaptcha validation to some of my apis.

To do so, I pass recaptcha token on these api requests from client side and then verify it on server side by following server side validation of recaptcha.

I am getting recaptcha token by executing below code and pass this token to my api request header:

const getRecaptchaToken = () => {
  return new Promise((resolve, reject) => {
    try {
      if (window.grecaptcha && typeof window.grecaptcha.execute === "function") {
        grecaptchaExecute(window.grecaptcha.execute);
      } else {
        window.grecaptcha.ready(async () => {
          grecaptchaExecute(window.grecaptcha.execute);
        });
      }

      // grecaptcha execute action
      async function grecaptchaExecute(ExecuteAction) {
        const captchaToken = await ExecuteAction(
          xxxxxx, // my recaptcha site key
          {
            action: "submit",
          }
        );
        return resolve(captchaToken);
      }
    } catch (error) {
      return reject(error);
    }
  });
};

Then, on server side I call:

`=${secret_key}&response=${captchaToken}`;

Most of time it is working fine, but some of calls randomly fail and return incorrect-captcha-sol error code.

Since it's happening randomly, I don't have a good idea when it is occurring and why. Also, I can't find the any details about this error code in the recaptcha documentations.

Any Ideas?

• 1 Not sure if this is your issue but I got this error when I was using a website that did not have HTTPS. – Greg Commented Aug 9, 2021 at 17:57
• 1 same issue here. I am using HTTPS and still getting it from time to time (less than 1% of requests). – Matanya Commented Oct 5, 2021 at 6:43
• I have the same problem, I read all related topics but didn't find any solution I also couldn't re generate the exception to find out what can we do in these cases. maybe getting a new token from google or something else. did you find any solution for that ? – Danial Jalalnouri Commented Oct 15, 2021 at 12:26
• 1 This link provides info about multiple ways you can get the error. So if you are doing testing several times a day then you might get the error cos their analytics might think you are a bot. Repasting the link so that people who can not see deleted answers get the info. – the Hutt Commented Feb 12, 2022 at 14:13

If it happens randomly and most of time it works fine you can usetry function so if it receives an incorrect-captcha-sol it will repeat until the code will work normally. Here is the code:

try {
   function Captcha(){
      const getRecaptchaToken = () => {
      return new Promise((resolve, reject) => {
      try {
      if (window.grecaptcha && typeof window.grecaptcha.execute === "function") {
        grecaptchaExecute(window.grecaptcha.execute);
      } else {
        window.grecaptcha.ready(async () => {
          grecaptchaExecute(window.grecaptcha.execute);
        });
      }
      // grecaptcha execute action
      async function grecaptchaExecute(ExecuteAction) {
        const captchaToken = await ExecuteAction(
          APIKEY, 
          {
            action: "submit",
          }
        );
        return resolve(captchaToken);
      }
    } catch (error) {
      return reject(error);
    }
  });
};
    }
 } catch (error) {

  Captcha();
 }
