I am trying to update a custom filed using put requests in POSTMAN
I manage to update the page title slug or any filed which wordpress created.(fields)
For example I have :
if I do a get request :
you will see :
    "acf": {
        "dog_name": null

What I want to do is update dog_name I have tried multiple solutions.
the PUT request echoes :
    "code": "cant_update_item",
    "message": "Cannot update item",
    "data": {
        "status": 500
Anyone solved this ?

I figured how to use the following plugin which if you read the GitHub instructions you will note that you can update fields if you
change the word acf in the JSON to the word fields .
original get will return the custom fields :
  "acf": {
    "filed1": "bay",
    "filed2": "2004",

But to update you have to change the word "acf "to fields like so (in the instructions they say how to change it):
  "acf": {
    "horse_colour": "bay",
    "birth_date": "2004",
    "sire_name": "sire name",
    "dam_name": "SNIPPETS",
    "sire_sire_name": "sire_sire_name dsd"
