Patch for <object> type

[AleksandrLiakhavetsEPAM]

Does the patch work for the object type? I tried this method but was unsuccessful...

Request:

[
  {"op": "replace", "path": "number", "value": 86632}
]

Handler

[HttpPatch]
public IActionResult Patch([FromBody] JsonPatchDocument patchDoc)
{
      var jsonData = """"
            {
                 "number": 1111
            }
             """";

      var obj = JsonSerializer.Deserialize<object>(jsonData)!;

      patchDoc.ApplyTo(obj);

      return Ok(patchDoc);
}

Exceptions

he target location specified by path segment 'number' was not found.

Good question, I havent tested this behavior.

Yeah this doesn't work because System.Text.Json deserializes object as JsonElement type and that type does not have writable setters.

You could however Deserialize jsonData as JsonNode

using System.Text.Json.Nodes;

[HttpPatch]
public IActionResult Patch([FromBody] JsonPatchDocument patchDoc)
{
      var jsonData = """"
            {
                 "number": 1111
            }
             """";

      var obj = JsonSerializer.Deserialize<JsonNode>(jsonData)!;

      patchDoc.ApplyTo(obj);

      return Ok(patchDoc);
}

Maybe that suits your need?
