set()the
projectskey to any empty array (or
unset(), not sure which).
Data looks like:

"contentArray": [
{
"_key": "3cd487d4bd8c",

Hi Steve. If you want to unset all the
Unset will remove the
projectsarrays inside of
contentArrayitems, you could use JSONMatch like:
import sanityClient from 'part:@sanity/base/client'
const client = sanityClient.withConfig({ apiVersion: '2022-04-05' })
client
.patch('9c780fd3-0e54-40ad-80c8-fd27dc19359f')
.unset(["contentArray[*].projects"])
.commit()
.then((res) => {
console.log(res, ' updated')
})
.catch((err) => {
console.error('Transaction failed: ', err.message)
})projectsarrays from the JSON, as is customary in Sanity when an array is empty.

(as usual!) … worked like a charm and I learned about JSONMatch to target items in patches like set(), unset(), etcApr 6, 2022, 7:35 AM
