Describe the bug

As seen in the image below, the reCAPTCHA verification does not seem to work. I always get the message "Bitte bestätigen Sie die Sicherheits-Abfrage" (German) which means "Please confirm the security query" in english.

debug.log says:

2025-03-20 20:52:12: Bitte bestätigen Sie die Sicherheits-Abfrage
2025-03-20 20:52:12: Recaptcha response Array
(
    [0] => missing-input-response
)

• For account creation it works
• For newsletter registration it works
• I have tried reinstalling and generating new keys on Google Cloud Console.
• I have tried with reCAPTCHA V2, but there I experienced the same issue.
• My backend says everything is good (Success).
• I'm using the latest Version 2.5.1 of the eicaptcha module.

Versions:
_Recaptcha version : 3
Prestashop version : 8.2.1
Theme name : classic
Php version : 8.1.31

Same problem - Prestashop 8.1.3, EiCaptcha 2.5.1 and for the V3 it does not load/validate the security form rendering in an error message when submitting the contact form messages. V2 works ok but will not screen out some spam bots.

Same problem :
error console : Uncaught (in promise) TypeError: Cannot set properties of null (setting 'value')
#captcha-box is undefined.

presta 8.2.0 - EiCaptcha 2.5.1

Exactly the same problem.
It blocks all submissions, even "human" ones.
FYI, PS 8.2
Theme via Creative Element...

I just ran a test without using the secret key on PS 8.2. The captcha appears correctly. I was able to send a message.
But I don't know if this is the solution. I'll wait and let you know if I receive spam again without this key.
What do you think of removing this secret key?

Well, ultimately removing the secret key isn't a good idea, it doesn't work, the spam continues... :/
