Recently disabled lookup_graph_lookup_foreign_becomes_sharded.js using checkSBEEnabled() function when featureFlagSBELookupPushdown feature is turned on. It turned out that checkSBEEnabled() can't detect reliably whether a SBE feature is turned on or not on the last-lts version (5.0).
So, we need to find another way to detect reliably whether a SBE feature is turned on or not on the last-lts.
But checkSBEEnabled()'s semantics is not good to detect whether a SBE feature is turned on on the last-lts version because the SBE is not turned on by default in that version and it will return false.
Proposed fix is to query featureFlagSBELookupPushdown value directly to the shard since there's only one shard in this test configuration.
The real test failure must be investigated by SERVER-64714.
Information from the BF ticket.
