Description

Hi,

using typecast

typeCast: function (field, next) { if (field.type === 'JSON') { let c = field.string("utf8"); <= this is causing the warning if (c && c.toLowerCase() !== "[null]") return (JSON.parse(c)); else return []; } return next(); }

brings up npm error

typeCast: JSON column "MyColumnName" is interpreted as BINARY by default, recommended to manually set utf8 encoding: field.string("utf8")

For every query which contains a JSON_ARRAYAGG command.

This is spamming the logs so I really need to get rid of it

sorry do not know how to format the code correct

Research direction

The report does not name a file or test. Start by reproducing the warning with a typeCast callback and a query containing JSON_ARRAYAGG, then trace the MySQL JSON-column handling. Done means the intended JSON result still works without repeatedly spamming the logs with the encoding warning.
