Not able to upsert using React Native fetch()

Support
2

I followed Node.js fetch upsert stopped working without me changing anything - #8 by shore

const response = await fetch(request);
console.log(request);
console.log(response);
if (!response.ok) {
    const details = await response.text();
    console.log(details);
    throw new Error(`HTTP error! status: ${response.status}`);
}

and got this!: {“code”:3,“message”:“Vector dimension 1536 does not match the dimension of the index 512”,“details”:}

so… case closed!
