populate with strategy: LoadStrategy.JOINED not work

PS: with Load Strategy JOINED work in version 5+

full stack trace?

Oh, so you are trying partial loading with joined strategy - that is not implemented in v4, but it is working with v5. You will need to upgrade if you want that. v5 is almost complete, definitely safe choice if you are starting new project or just trying out things. Also both populate and fields are strictly type checked in v5, so you would not fall into those issues with typos.

And I was asking about those stack traces:

I get error 'TypeError: Cannot read property 'orderBy' of undefined' if indicated wrong

Get error 'TypeError: Cannot read property 'reference' of undefined' if miss one letter

I am keeeping this open only for possible added error handling/validation. If you are not going to give me the reproductions for those errors I asked for, we can close this 🤷

Tried to intentionally make typos in both populate hint and fields, but they both don't produce those error you were talking about, they fail with either populate validation or with a wrong fields in SQL query, both is fine to me. Maybe those cases are already handled in v5 correctly.

Will be happy to reopen if you can show me how to get to those ugly and unclear errors.
