Square API: Object version does not match latest database version - square

Question

I'm trying to use the following Square API endpoint to update an item, but I'm getting some errors. Here is the item that I'm trying to update.
{

}
}
}
],
"product_type": "REGULAR",
"skip_modifier_screen": true,
"ecom_available": false,
"ecom_visibility": "UNINDEXED"
}
}
Here the body content.
{
"batches": [{
"objects": [{
"type": "ITEM_VARIATION",
"id": "T6KKCATDIU2VV4BDBMVGML4W",
"item_variation_data": {
"item_id": "FNWWGFTBQWFAYK6JGBD3LDLD",

"price_money": {
"amount": 150,
"currency": "USD"
}
}
}]
}],
"idempotency_key": "61994762-3a6s-4b75-sf81-fdfaf"
}
Here is the error I'm getting:
**{
"errors": [
{
"category": "INVALID_REQUEST_ERROR",
"code": "VERSION_MISMATCH",
"detail": "Object version does not match latest database version.",
"field": "version"
}
]
}**
I'm not sure what I'm doing wrong, but I appreciate any help I can get. Thank you in advance!

When updating a catalog object in Square, you need to provide the latest version number in the request.
{
"batches": [{
"objects": [{
"type": "ITEM_VARIATION",
"id": "T6KKCATDIU2VV4BDBMVGML4W",
"version": "12345",
"item_variation_data": {
"item_id": "FNWWGFTBQWFAYK6JGBD3LDLD",
"pricing_type": "FIXED_PRICING",
"price_money": {
"amount": 150,
"currency": "USD"
}
}
}]
}],
"idempotency_key": "61994762-3a6s-4b75-sf81-fdfaf"
}
