OData filter by Date throws "The query specified in the URI is not valid. An identifier was expected at position 62"

Question

I am using OData to query data from my SQL Db, I am trying to filter data using a Date value. See query below:

http://localhost:4409/OrderMaintenance?$filter=DocType%20eq%205%20and%20DocState%20in%20(0,1,2,3,4,5,6,7)%20and%20InvDate%20eq%202022/02/21

Only the date is the problem in this query because when I remove the date filter the query works fine.

The InvDate is of type:

orderDateFilter: Date = new Date();

I then formatted the date to:

this.orderDateFilter.toLocaleDateString()

which returns date as :

2022/02/21

But I am getting the following error

"The query specified in the URI is not valid. An identifier was expected at position 62."

Try to format the odata date filter with dashes instead of backslashes: 2022-02-21 instead fo 2022/02/21. You might also need to add the time portion. Here's an example with time at midnight 2022-02-21T00:00:00Z.
