I disabled WP_Debug and it disappears, apologies I suppose this is a wp core issue, actually it’s traced backwards as a warning from wp core. triggered by ACF, due to submitting invalid data to ACF, so yes WP Core should be updated to use the newer php function, but the initial trigger comes from sending a badly formed array object. probably lazy coding imho. but I don’t want to read through your code to find out why. not a critical factor

take a look at this screen shot for an example, I don’t have debugging turned on it appears in the admin panel itself. I think your plugin code is trying to leverage a WP function but isn’t providing valid input parameters. perhaps not properly checking for null values
