Custom Action Opens a Preview URL on Wrong Domain

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 , I just updated it with a gist of the correct one.

I have a client studio that has this:

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?

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.

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 ! 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

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)
