Custom Action Opens a Preview URL on Wrong Domain

Last updated: Jan 31, 2022
Hey there, I have a custom action that opens a preview URL, but it keeps opening my URL at the studio domain, instead of the one specified…

You can see it here, it’s supposed to use the 
remoteURL
but on deployed studios it’s now opening it without this, causing it to open the 
/api/preview?token=xxx
at the studio domain

sorry, wrong example
user A
, I just updated it with a gist of the correct one.

I have a client studio that has this:
Jan 31, 2022, 6:48 PM
const remoteURL = '<https://xxx.vercel.app>'
const localURL = '<http://localhost:3000>'
const frontendURL =
  window.location.hostname === 'localhost' ? localURL : remoteURL

and it’s opening it at 
<https://xxx.sanity.studio>

Don't suppose there is any chance you are viewing it from 
127.0.0.1
or 
0.0.0.0
or some other local, non-localhost hostname? 😅

(maybe 
window.location.protocol === 'http:' ? localURL : remoteURL
would be slightly more robust in this case?)

seems to only be on a deployed studio for some reason

How is the 
remoteURL
getting set? Statically? Environment variable?
Jan 31, 2022, 7:32 PM
going to try clearing node_modules and dist to see if it helps!

static

Super weird. There is nothing Sanity-specific about the code that determines the URL or opens the window, as far as I can tell from your gist.
Jan 31, 2022, 7:34 PM
If I were to guess, the 
remoteURL
is somehow null/empty string, but if it's defined statically that doesn't make sense

thanks for clarifying
user Z
! I’m wondering if checking 
localhost
is for whatever reason erroring when deploying

I just redeployed again, and hard refreshed and this time it’s taking the correct domain name
Jan 31, 2022, 7:36 PM
it’s just super odd since I was able to reproduce on the deployed studio after the client alerted me to it (which I had just showed them how to preview last week using the deployed studio during a previous build)
