Problems with using SendGrid

I created a custom form and am using SendGrid to send an email to my client on form submission. It was working up until Friday. Now Sendgrid is showing my emails are still being delivered but I am getting this message in inspect/console:
Failed to process file ‘/public/pages/eqsxu.js’. Access to backend script ‘backend/sendGrid.js’ denied!

Any thoughts?

Are you still encountering this issue?

Except for the error message, is everything working as it should? If not, what isn’t working?

Yes. No emails have been sent since Friday. SendGrid thinks there could be a problem with the js file?

It’s working again. Thanks!
