HTTP 404 on `/_vercel/insights/script.js`

[agurtovoy]

Firstly, thank you for offering built-in analytics support, this by itself makes it worth upgrading to Pro for me!

I followed the steps in the Audiences Quickstart Guide, including redeployment, but I'm still getting 404 on a GET for /_vercel/insights/script.js:

... and, consequently, my production dashboard shows 0 visitors:

Interestingly enough, my preview deployments don't have this issue and are actually able to track visitors, but I think it's because they are doing it through a slightly different mechanism:

I saw that https://github.com/vercel/analytics/issues/1 was confirmed as resolved by people who were experiencing it earlier, so thought I'd open a new issue.

Hey @agurtovoy! I just looked into this, it seems like you did deploy to production before analytics got enabled. Can you please try redeploying production and check if its working afterward.

Thanks :)

Hey @tobiaslins, thanks so much for the quick response!

Redeployment did fix this, and I think I know what I did wrong: I redeployed after enabling Vercel Analytics, which is the prompt that is shown by default when you click on a project's Analytics tab, but I guess one also needs to redeploy after enabling Audiences.

The docs say as much, but, unlike the Vercel Analytics dialog, there is no explicit "Redeploy" button when you enable Audiences, so if you add this package first and then enable Audiences, you'll get a 404:

Vercel Analytics prompt	Audiences prompt

It's definitely a user error, but perhaps there is something you could do with the UX to make this more clear.

Thanks again for the prompt reply!

Thank you for the feedback! We're currently improving the setup flow because it can be confusing at the moment!
