Execute a MySQL command with named parameters

Steps to reproduce

1. Install node v12.19.0
2. Install package "loopback-connector-mysql": "6.0.0"
3. use repository that extends DefaultCrudRepository and run:
   await repo.execute("SELECT * FROM table WHERE name = :name", {name: "John Doe"})

Current Behavior

Receive error:
strong-error-handler Handling AssertionError [ERR_ASSERTION]: params must be an array

Expected Behavior

According to doc the type NamedParameters is supported, so object should be handled

Additional information

Related Issues

I have found https://github.com/strongloop/loopback-next/issues/5264 which is related if the problem is in documentation

Start with DefaultCrudRepository.execute and the NamedParameters API documentation, then trace the call through legacy-juggler-bridge.js to loopback-connector/lib/sql.js, as shown in the stack trace. Compare the documented parameter contract with the MySQL connector behavior; done means named parameters either execute successfully or the documentation accurately states the supported form.
