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'
                        }
                    ]
                }

            ]
