Hi Team  
I am currently facing an issue while utilizing readable synonyms from a file with my completion suggestor. The problem seems to be related to the search\_analyzers in my mappings. Strangely, the completion suggestor works fine when I use it with the \_analyze API.

I would like to provide you with the mappings and suggestor details that I am using:

```auto
"master_synonyms": {
          "type": "synonym_graph",
          "synonyms_path": "search_synonyms/master_synonyms.txt",
          "updateable": true
        },

```

```auto
"synonym_analyzer": {
          "filter": [
            "lowercase",
            "asciifolding",
            "master_synonyms"
          ],
          "tokenizer": "standard"
        },

```

```auto
"smartSuggestor": {
      "type": "completion",
      "analyzer": "smart_analyzer",
      "search_analyzer": "synonym_analyzer",
      "preserve_separators": true,
      "preserve_position_increments": true,
      "max_input_length": 100,
      "contexts": [
        {
          "name": "hybrid-context",
          "type": "CATEGORY",
          "path": "contextMapperFilter"
        },
        {
          "name": "provider-context",
          "type": "CATEGORY",
          "path": "provider"
        },
        {
          "name": "subCategory-context",
          "type": "CATEGORY",
          "path": "contentType.subCategory"
        },
        {
          "name": "category-context",
          "type": "CATEGORY",
          "path": "contentType.category"
        }
      ]
    }

```

```auto
ker,kera,keral,kerala=>Malayalam
chand,chandi,chandig,chandiga,chandigar,chandigarh=>Punjabi
guj,gujj,gujju=>Gujarati
bihari,bihar=>Bhojpuri
Karna,Karnat,Karnata,Karnatak,Karnataka=>Kannada

```

I am encountering this issue in my current implementation, and it is impacting the functionality of the completion suggestor. I have checked the \_analyze API, and it seems to be functioning as expected with the synonyms from the file.

Also if I am using mapping the synonyms directly without using the file it is working fine with the suggestors.

Any insights or potential solutions you can provide to address this issue would be greatly appreciated.

Thank you for your prompt attention to this matter. I look forward to your guidance.

Please find the error below:

```auto
Caused by: java.lang.NullPointerException: Cannot invoke \”org.elasticsearch.index.analysis.AnalyzerComponents.getCharFilters()\” because \”components\” is null
