Calling _api/search/postquery from Modern Web Part (security validation invalid)

I am trying to call /_api/_search/postquery from a modern Script Editor web part, and I am getting this error:   VM6497:86 {"error":{"code":"-2130575251, Microsoft.SharePoint.SPException","message"...

    I've found that if I make POSTs from a different site (or site collection) than the REST URL target, my on page RequestDigest won't do. I need to grab a fresh one from the target site _api/contextinfo.

     

    Not sure if this is your issue, but worth a try.

Well, magically, I come in today, and now this is working as it should. Not sure why it wouldn't work yesterday.
