Entity - Incompatible Runtime

behaviorpack.entity.incompatible_runtime

A specified component is incompatible with the entity's runtime identifier.

Example

The following will result in an error:

{
  "format_version": "1.16.0",
  "minecraft:entity": {
    "description": {
      "identifier": "example:foo",
      "runtime_identifier": "minecraft:dolphin"
    },
    "components": {
      "minecraft:movement.basic": {}
    }
  }
}

The runtime minecraft:dolphin adds the component minecraft:movement.dolphin to the entity. There being two movement components causes an error.
