Indeed.  It looks like this is where it's used:

(defun sql-auth-source-search-wallet (wallet product user server database port)

[...]

    (let* ((auth-sources wallet)

and auth-source-search assumes that auth-sources is a list of
... things, not a string:

(cl-defun auth-source-search (&rest spec
                              &key max require create delete
                              &allow-other-keys)

[...]

  (let* ((backends (mapcar #'auth-source-backend-parse auth-sources))
