Flex:rpc error: code = PermissionDenied:preparePerms err: index not found

Build: 7.0.0-5129

• Create cluster with kv, kv+query, fts
• Load travel-sample
• Create fts index like below:

  {

  "type": "fulltext-index",

  "name": "second",

  "uuid": "60f5a5a0cff8b73a",

  "sourceType": "gocbcore",

  "sourceName": "travel-sample",

  "sourceUUID": "3e5d5b07817a2a96a5f0b7d334cd382d",

  "planParams": {

  "maxPartitionsPerPIndex": 1024,

  "indexPartitions": 1

  },

  "params": {

  "doc_config": {

  "docid_prefix_delim": "",

  "docid_regexp": "",

  "mode": "type_field",

  "type_field": "type"

  },

  "mapping": {

  "analysis": {},

  "default_analyzer": "keyword",

  "default_datetime_parser": "dateTimeOptional",

  "default_field": "_all",

  "default_mapping": {

  "dynamic": true,

  "enabled": true

  },

  "default_type": "_default",

  "docvalues_dynamic": false,

  "index_dynamic": true,

  "store_dynamic": false,

  "type_field": "_type"

  },

  "store": {

  "indexType": "scorch",

  "segmentVersion": 15

  }

  },

  "sourceParams": {}

  }

• Run Flex query: select meta().id from `travel-sample`._default._default USE INDEX(USING FTS) where name = 'Atifly' . It returns below results:

  [

  {

  "id": "airline_10226"

  }

  ]

• Now, delete the fts index
• Run the same query again. It throws below error:

  [

  {

  "code": 5000,

  "msg": "n1fty: response_handler: stream.Recv, err - cause: rpc error: code = PermissionDenied desc = grpc_server: Search err: grpc_auth: auth err: grpc_auth: preparePerms err: index not found",

  "query": "select meta().id from `travel-sample`._default._default USE INDEX(USING FTS) where name = 'Atifly'"

  }

  ]

• Explain of the same query shows its trying to get results from deleted index
