compatibility issue with mysql aurora 8.0.* using regex

[cloud20x]

Steps to reproduce

• build a loopback datasource in a current mysql aurora (8.0.27 in my case)
• run a regex search:
  https://foo.bar.com/api/foo?filter={%22where%22:%20{%22name%22:%20{%22regexp%22:%20%22/^foo/%22}}}

Current Behavior

results in an "500 Internal Server Error":

Request GET /foo?filter=%7B%22where%22:%20%7B%22name%22:%20%7B%22regexp%22:%20%22/%5Efoo/%22%7D%7D%7D failed with status code 500. Error: UNKNOWN_CODE_PLEASE_REPORT: Character set 'utf8mb4_general_ci' cannot be used in conjunction with 'binary' in call to regexp_like.

Expected Behavior

Should return all regex matches for the selected model in the api response
