Describe the Bug

Both deep filtering syntax doesn't work anymore in v9.0.0. An empty translations array is returned even if entries should match.

GET &deep[translations][_filter][languages_code][_eq]=fr-CH

Results:
data: { translations : [ ] }

and

GET &deep={ "translations": { "_filter":  { "languages_code": {"_eq": "fr-CH" }  } } }

Results:
data: { translations : [ ] }

To Reproduce

Try to filter a collection that has the default relational translations applied.

Hello @gkielwasser
It seems a duplicate of #9578
But you already have commented there, so why did you open this?
Is this different in any way from the other one?

Hello @joselcvarela,

I thought it would be related but talking with @kwiatkk1 it seems not.

My ticket describe a bug using one of the default 2 deep filtering syntax exposed in the documentation.

The other ticket, from what I have understood seems to describe a deep filtering using a syntax where "_filter" and "translations" field is swapped from what it should be according to the documentation. I'm still not so sure I have understood well, but I let the author clarify that again.

Closing as it is indeed a duplicate of #9578
