* Hi David,
* Our server is ubuntu nginx php7.4-fpm
* When submitting the gravity form the user gets a critical php error right before
the success confirmation redirect and the email.
The submission actually is
successful, the post is created with all the data including all the keywords
entered into the taxonomy field. It just fails before the emails get sent or
the success page is shown so users keep re submitting 🙂
* The error from our log file:
* PHP Fatal error: Uncaught TypeError: array_key_exists(): Argument #2 ($array)
must be of type array, GF_Field_HTML given in /wp-content/plugins/gravity-forms-
custom-post-types/gfcptaddonbase.php:468

* Any ideas?
* The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmust-be-of-type-array-gf_field_html-given%2F%3Foutput_format%3Dmd&locale=en_US)

* Hi [@gaborkukucska](https://wordpress.org/support/users/gaborkukucska/), sorry
for the delay getting back to you!
* I had a hard time reproducing the exact error you are running into, but I put
a speculative fix into 3.1.20, which I’m hoping will help. 🙂
* Let me know how it works for you!
