Bulk convert gets stuck – Unexpected EOF

Attempting to bulk convert images on my site. There are a LOT of them so not sure if that is part of the problem. It is also running imagick with webp support on NGINX which I have set up and tested and the plugin says is active.

When trying to bulk convert the converter just gets stuck on ‘receiving list of files to convert…’ and this error is logged in the console:

SyntaxError: JSON Parse error: Unexpected EOF

var bulkInfo = {
‘groups’: JSON.parse(response), <– this line

I tried logging the response in the console but it just returns blank.

Not sure if this is a known issue or if there’s something obvious I’m missing?

Thanks!
