Discussion about resolving a BrowserslistError in package.json

BrowserslistError: Unknown browser query

dead

I was getting this error, even with all updated packages.

In your

package.json

, do you have a

browserslist

option? If so can you share it?

no, doesn't have.
here you can look at:

Hmm, some of those packages aren't from Sanity, so I can't be sure that they're not relying on an outdated browserlist. Can you try the solution in this article to see if it helps?

I tried this and no success 😢

I think I'll try to build from scratch

fixed when I inserted the
"browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [] }

inside my package.json.

I have to make yarn upgrade as well
