[BUG]

What is the bug?

Related to #956 , should aggs be supported in nested aggregations?

How can one reproduce the bug?

await client.search({
  index: 'news',
  body: {
    query: {
      bool: {
        filter: [
          { term: { 'locale.keyword': 'en' } },
        ],
      },
    },
    aggs: {
      spendAggregationsByCurrency: {
        terms: {
          field: 'currency.keyword',
        },
        aggs: { <-- throws error 'aggs' does not exist in type 'AggregationContainer'
          totalSpend: {
            sum: {
              field: 'adCost',
            },
          },
       }, 
    },
    size: 0,
  },
})

What is the expected behavior?

For aggs to be supported

Do you have any screenshots?

Additional question

Considering the big release of opensearch-project v3 was revolved around the opensearch API specification generator, should it only support aggregations moving forward? or aggs is expected to continue working?

If the server still supports it then yes. Please do contribute!

Shall we close this issue @Xtansia ?

@xavianaxw Should likely leave the issue open until the changed spec actually gets pulled in via the next code generation run. (cc @nhtruong)
