We're sometimes seeing an undocumented incorrect-captcha-sol error returned when verifying reCAPTCHA v3 responses:
{
"success": false,
"error-codes": [
"incorrect-captcha-sol"
]
}
Some research has revealed a few others that have run into this same issue but with no official resolution:
- https://2captcha.com/blog/google-doesnt-accept-recaptcha-answers
- https://github.com/AurityLab/vue-recaptcha-v3/issues/535
Since the incorrect-captcha-sol error is not documented we're unsure how to handle this situation. Any advice would be greatly appreciated.
