ft.aggregate does not aggregate when filtering tags

[kvamsij]

Description

flavour is a tag and it is array of strings. This how I declared in schema ( $.sfl.[] as flavour TAG SEPARATOR ','). I can see the results without aggregation step but with aggregation i get an error message Value was not found in result
` const { results, total } = await client.ft.AGGREGATE(redisIndex, '', {
LOAD: ['@dataset', '@region', '@Country', '@flavour'],
STEPS: [
{
type: AggregateSteps.FILTER,
expression: '@dataset == 1'
},
{
type: AggregateSteps.FILTER,
expression: '@region == "US"'
},
{
type: AggregateSteps.FILTER,
expression: '@flavour == "Chocolate"'
},
{
type: AggregateSteps.GROUPBY,
properties: ['@Country'],
REDUCE: [
{
type: AggregateGroupByReducers.COUNT,
AS: 'count'
}
]
}

        ]
    })`
