No setting can put a post into the block editor if its post type does not support it. That is the most common reason a custom post type “ignores” the default.
editor/get-post-type-editor-support reports, for each post type, whether the classic editor and the block editor are available to it.

How it works
The classic editor needs the post type to support editor. The block editor needs the post type to be block-editor eligible, which usually means it is registered with show_in_rest.
Post type support has the last word over the site default, the user preference and any remembered choice.
Omit post_type to inspect every registered post type at once.
Input
| Name | Type | Required | What it is |
|---|---|---|---|
post_type | string | No | One post type. Omit for every registered post type. |
What comes back
| Name | Type | What it is |
|---|---|---|
post_types | array | One row per post type: whether the classic editor and the block editor are available, and whether neither is. |
count | integer | How many post types were inspected. |
success | boolean | Whether the call completed. |
message | string | A one-line summary of what happened, suitable for showing a human. |
error_code | string | Present only on failure — a stable machine-readable reason, such as a missing field, a wrong field type or an unmet confirmation. |
Example
Ask your assistant:
Why won’t our Events post type use the block editor?
It resolves to one call:
{
"ability": "editor/get-post-type-editor-support",
"parameters": {
"post_type": "event"
}
}Worth knowing
- A post type with neither editor available has no content editor at all — usually on purpose.
- Run this before changing any setting: if the post type is not eligible, no setting will help.
