Hi nok 

simialr issue :

looks like he Put the query pairs into the Query section, not the Relative path section. and got it sorted :https://community.fabric.microsoft.com/t5/Power-Query/Help-with-syntax-One-or-more-table-references-a-dynamic-Data/td-p/3134545

so adding only Relative path only is not sufficent it seems you will need to add the query section as well 

check this arlticle as well :

Using OData.Feed And The Query Option To Avoid The Dynamic Data Sources Error In Power BI

so i'm guessing it must be something similar to this 

let
    dateCurrentDay = DateTime.LocalNow(),
    dateTwoYearsAgo = Date.AddYears(dateCurrentDay, -2),
    dateFormat = DateTime.ToText(dateTwoYearsAgo, "yyyy-MM-ddTHH:mm:ss.99Z"),
    
    Source = OData.Feed(
        "https://api.myodata.com/xx/v7/TableRequest", 
        null, 
        [
            Implementation = "2.0", 
            Query = [#"@updatedDate" = "cast(" & dateFormat & ",Edm.DateTimeOffset)"]
        ]
    )
in
