Power BI Embedded Report GetFilters Bug

Javascript: powerbi-client v2.7.4

report.getFilters() returns {"message":"Invoked filter serialization function with no filter."}

when the report filter is set to all and filter type is "relative date filtering".

Issue is only when filter is set to ALL. if the filter is applied it returns values properly

{"$schema":...},"filterType":4,"operator":0,"timeUnitsCount":30,"timeUnitType":0,"includeToday":true}
