Getting ValidationException: Invalid FilterExpression when publishing a big objects

[eitanfr]

I am getting "ValidationException: Invalid FilterExpression: Expression size has exceeded the maximum allowed size" when I try to publish a large object.

It looks like the issue is happing because of the filter logic, in getFilteredSubs.ts. Because I try to publish big a big object with nested objects inside the function creates a massive filter expression which results in the "Invalid FilterExpression: Expression size has exceeded" error.

In my use case, I don't need the filter nested logic, seems like a possible solution is to allow configuring to filter nested objects.
For example, I only need to filter by one argument (like userId).
