I have implemented google-recapthca in angular 5 and it working well for all browers but in safari i got following error:
my safari version is : 12.0
my html code
<div class="g-recaptcha" id="gAuth" data-sitekey="your_site_key_here"></div>
Do you have Adblock on? I've seen the error before and it seems like AdBlock can cause this error.
Optionally you can check this thread out: https://github.com/google/google-api-javascript-client/issues/397
Seems like the issue can be caused by multiple things.
