Data View is no longer returning results

I have a Data View which returns records grouped by a user id (qocID in the code). I have returned the results into a table filtered by a selection from a Select dropdown.

Here is the data-view code

<dmx-data-view id="qoc_view" dmx-bind:data="scEntries.data.entry.groupBy(qocID)" filter="($value[0].ageID == sel_agegroup.value.toNumber())"></dmx-data-view>

For testing I have entered explicit value (ex $value[0].ageID == 1 ) as well as the code above. This used to work without error, now any value entered in the filter code results in zero records returned. When I remove the filter all records display as anticipated.

I believe this is a similar issue to one I had earier ( https://community.wappler.io/dynamic-dropdowns-suddenly-returning-undefined/42095?u=lwoolsey )
