Problem with combining sources via date parameter in GDS?

Question

Analytics

Task: I need to merge two data sources in Google data studio. Each of them has such a parameter as a date. While I use the association only by the seller id parameter - everything is ok, as soon as I add the second parameter in the form of a date - an error occurs

This data source is not configured correctly.

Invalid argument type.

Error ID: c504a5e6

Dates in the same format Example: 12 Jan. 2022

If you do not specify the union key by date, then the summation of the column with the number of dialogs occurs without taking into account the date.
