Summary\n\nCloses https://github.com/elastic/kibana/issues/224596\n\nThe
“View related errors” link in the full-screen waterfall was\nresolving
to an invalid ES|QL query in some specific scenarios (it\nworked fine in
edge-oblt, for example).\n\nTo work around this and make the query less
restrictive for ES|QL, we’ve\nupdated it to use `QSTR` instead. It
provides the same type of search\nand gives us the expected results
without triggering errors.\n\n**Before**\n![Screen Recording 2025-06-20
