Troubleshooting GROQ query integration with React and Electron in Slack thread

Hi all, am just looking at integrating Sanity with React in a really basic way for proof of concept testing for a desktop app using Electron.
I was just wondering what the most straightforward GROQ query usage would be to do this?

I was using essentially the query from the React Native git repo which I have working on another POC experiment. But when the query is called I get the following:


But the query url is working fine:

Any clues what I'm missing here?

I believe you have to add

null

to CORS origins?

In the fetch you mean?

On manage.sanity.io => Settings => API

As in like this? Sorry if this is a silly question!

Yup! There is no such thing as a silly question:)

Does the studio need redeployment after that or is it automatic.
And thanks
I’ve tested that idea a little in the past :)

No redeployment needed. This only affects the backend

Will double check later and report back

- after all that it was a localhost issue. Added

<http://localhost:3000/>

and we're in business.
But thanks for your help, that set me on the right track and I appreciate it!

Aha. I thought electron apps wanted

null

but awesome that you figured it out!

Thanks again
