Does this answer your question? [System.Text.Json.JsonElement ToObject workaround](https://stackoverflow.com/questions/58138793/system-text-json-jsonelement-toobject-workaround) — JHBonarius, Jan 20 '23 at 09:06
You can use [`.GetProperty("otp")`](https://learn.microsoft.com/en-us/dotnet/api/system.text.json.jsonelement.getproperty) to access the internal element. That will return a new `JsonElement`, which is a string. So use `.GetString()` on that. But the better (=C# like) answer is [here](https://stackoverflow.com/a/59047063). You need to deserialize the `JsonElement` to a proxy class or a `Dictionary` (or `Dictionary` for this simple type). — JHBonarius, Jan 20 '23 at 09:11

As your Quick Watch shows:

When you use dynamic here, it won't be deserialized to an object with the properties in json, but will return a JsonElement.

You can use its methods to parse the json as you like. Meanwhile you can just receive it like [FromBody] JsonElement opt.

ah, of course. dumb of me. It should even be `[FromBody]string opt`, as `JsonElement` is not needed at all. – JHBonarius Jan 20 '23 at 10:46
