Multiple files upload not working

[comzeradd]

Hi,

When enabling "Multiple Files" on a File field, uploading files doesn't work and raises and exception.

"NOTICE: PHP message: PHP Fatal error:  Uncaught TypeError: strpos(): Argument #1 ($haystack) must be of type string, stdClass given in wp-content/plugins/wp-stateless/lib/classes/compatibility/gravity-forms.php:92"
"Stack trace:"

"#1 wp-includes/class-wp-hook.php(326): wpCloud\StatelessMedia\GravityForm->gform_save_field_value()"
"#2 wp-includes/plugin.php(205): WP_Hook->apply_filters()"

"#4 wp-content/plugins/gravityforms/forms_model.php(3488): gf_apply_filters()"

"#6 wp-content/plugins/gravityforms/forms_model.php(6855): GFFormsModel::create_lead()"
"#7 wp-content/plugins/gravityforms/..."

This is tested with Gravity Forms 2.8.13. I know documentation says latest tested version is 2.7.17.1, but that's a really old version and didn't have that available to test it.

Hello @comzeradd

Do you use this Addon WP-Stateless – Gravity Forms Addon https://wordpress.org/plugins/wp-stateless-gravity-forms-addon/ ?

It has compatibility with Gravity Forms plugin version 2.8.9

We will update information here https://stateless.udx.io/addons/gravity-forms/ soon, thanks for pointing this out.

I just installed the addon and re-tried. I'm still getting a similar error but it's now triggered by the addon code.
