Elastic.Transport.UnexpectedTransportException with Indices.GetAsync

[LearnC0de]

Elastic.Clients.Elasticsearch version: 8.15.0

Elasticsearch version: 7.17.9

.NET runtime version: 8.0

Operating system version:

Try to use await client.Indices.GetAsync(....) and it throws
Elastic.Transport.UnexpectedTransportException : The JSON value could not be converted to System.Collections.Generic.ICollection`1[System.String]. Path: $.char_filter | LineNumber: 0 | BytePositionInLine: 51

Steps to reproduce:
I have an index with a filter in settings:

"settings": {
.......
"analysis": {
"filter" : {
"char_filter" : {
"space_brackets_hypen_dot" : {
"pattern" : "[\s*().-]",
"type" : "pattern_replace"
},
"digits_only" : {
"pattern" : "[^\\d]",
"type" : "pattern_replace"
},
"digits_only_space_replace" : {
"pattern" : "[^\\d]",
"type" : "pattern_replace",
"replacement" : " "
}
},
},
}
}

Expected behavior
Should be able to get back index definition

Hi @LearnC0de, please post the complete exception call stack.

And please format and indent the JSON payload next time you open an issue. It's extremely hard to read this way. I tried to reformat it:

{
  "settings": {
    "analysis": {
      "filter": {
        "char_filter": {
          "space_brackets_hypen_dot": {
            "pattern": "",
            "type": "pattern_replace"
          },
          "digits_only": {
            "pattern": "[^\\d]",
            "type": "pattern_replace"
          },
          "digits_only_space_replace": {
            "pattern": "[^\\d]",
            "type": "pattern_replace",
            "replacement": " "
          }
        }
      }
    }
  }
}

For me it looks like these index settings are invalid in the first place. You define the filter under settings.analysis.filter.char_filter, but IMO this should be changed to define them all under settings.analysis.filter.

Hi @flobernd

Sorry for the incorrect setting above. Please see the correct index setting below

{
   "analysis":{
      "char_filter":{
         "space_brackets_hypen_dot":{
            "pattern":"[\\s*().-]",
            "type":"pattern_replace"
         },
         "digits_only":{
            "pattern":"[^\\d]",
            "type":"pattern_replace"
         },
         "digits_only_space_replace":{
            "pattern":"[^\\d]",
            "type":"pattern_replace",
            "replacement":" "
         }
      }
   }
}

Hi @LearnC0de, thanks for providing the full callstack. This helped to narrow down the exception.

It seems that the deserialization failure is not related to settings.analysis.char_filter, but instead related to settings.analysis.analyzer.

Could you please check if you have any analyzer configured and if yes, please post the corresponding JSON payload here as well.

Hi @LearnC0de, thanks for the requested analyzer settings!

It seems like this is an issue in the specification that is used to generate large parts of the clients.

The value of the filter and char_filter fields is sometimes returned as a single string instead of string[], if they contain exactly one element.

Fixed in 8.15.1. Thanks for reporting @LearnC0de! Please let me know, if this resolves your issue.
