Best practices for handling planetscale DatabaseErrors with Drizzle?

import { DatabaseError } from '@planetscale/database';
// ...

try {
    const isUserCreated = await this._userService.signUp(body);
    return Respond.success(isUserCreated, { code: HTTPStatusCodes.Created201 });
} catch (e) {
    if (e instanceof ApiError) {
        return Respond.error(e.code, e.message, { details: e.details });
    } else if (e instanceof DatabaseError) {
        switch (e.status) { /* <- Is this the Mysql error code? */
            case MySQLErrorCodes.ER_DUP_ENTRY:
                // retry x times
                break;
            default:
                return Respond.serverError('An error occured in the database', {
                    details: e.body
                });
        }
    }
    console.error(e);
    return Respond.serverError('Unknown server error', e ? { details: e } : undefined);
}

const errnoMatch = err.body.message.match(/errno (\d+)/);
if (errnoMatch) {
    const errno = parseInt(errnoMatch[1]);
    // Compare errno to MySQLErrorCodes enum
}
