Hi @mawill13,
I suppose you are trying to create a Config under Smush > Settings > Configs, right?
Could we know you notice the above error when you try to create a Config or when applying it?
WP JSON is part of REST API, the 404 error points there is a conflict, is there any plugin that disables Rest API on your website? or do you have any security plugin?
I gave a quick test by creating config and by applying but wasn’t able to replicate any such issue. Could you please try running a conflict test and see whether that helps in ruling out what exactly might be causing the issue?
Please check the following flow chart on how to run a conflict test:

Please do let us know how that goes.
Kind Regards,
