Error: Encoding not recognized: 'cesu8' (searched as: 'cesu8')

[lnxfsf]

I'm using jest, and trying to test login, but apparently, it also need to establish sequelize MySQL connection.

It's about Encoding not recognized: 'cesu8' (searched as: 'cesu8')",

I've searched some "solutions", but none of them work.
1, 2

In case, of trying this solution require('mysql2/node_modules/iconv-lite').encodingExists('foo'); , I don't know what to put in "foo" ? If I put "cesu8", it's not supported, because truly there's nothing in that node folder , I checked, that would support. It's just utf16 , utf32 ,etc...

Neither this

• Please help, without this, I'm completely unable to test anything in my app

• Error after running npx jest

Attempted to log "ErrorSequelizeConnectionError: Encoding not recognized: 'cesu8' (searched as: 'cesu8')".
