I have strings that looks like this.
setting-bs_b77f423715d2b991-node
setting-bs_b77f423715d2b991-eggs
setting-bs_b77f423715d2b991-cheese
setting-bs_b14835f519bf447d-ham
How do I extract just the middle element? e.g. bs_b14835f519bf447d
it is always the same length and always has the same bs_
prefix.
I unfortunately cannot use a lookbehind for this problem, as suggested in this answer as the regex must run inside bigquery which does not support lookbehinds

Assuming you have no other 16-char alphanumeric words then [a-z0-9]{16}
could work.
