Fatal error: Uncaught TypeError: json_decode(): Argument #1

[iouston]

Hi,
I'm using acf-image-aspect-ratio-crop on a wordpress 6.4.3 website with acf-image-aspect-ratio-crop 6.0.3.
The website server is on php 8.0
I have an error message on a custom template page

Fatal error: Uncaught TypeError: json_decode(): Argument #1 ($json) must be of type string, array given in /home3/sc2iouston/public_html/wp-content/plugins/acf-image-aspect-ratio-crop/fields/class-npx-acf-field-image-aspect-ratio-crop-v5.php:886

I don't understand why.
Can you help me please ?
