Export extension not working: 503

Just trying a JSON export with no query, no sort, and any number of fields:

{
    "statusCode": 503,
    "error": "Service Unavailable",
    "message": "Failed to perform search."
}

I expect this is related to the ManagementAPI index failures?
Tried this from managementAPI. It looks like search engine v2 is 503 unavailable. Works with searchengine v1. Since we can’t set this in the export extension, it is a blocker.

As you mentioned yourself in your subsequent comment, the export extension depends on the user search functionality that is currently experiencing some issues. To obtain additional information you can check the related status page incident, if you haven’t done so already.

Yes. The status page until this morning didn’t indicate any particular issue with this API beyond newer records not being available.
