Root Cause

An ingest pipeline processor references a field that is not declared in the pipeline's field list or is missing from the source document.

摄取管道处理器引用了在管道的字段列表中未声明或源文档中缺失的字段。

Workarounds

  1. 95% success Update the pipeline to include the required field in its definition: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default" } } ], "version": 1 }`. 
    Update the pipeline to include the required field in its definition: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default" } } ], "version": 1 }`.
  2. 85% success If the field is optional, add an `if` condition in the processor: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default", "if": "ctx.my_field != null" } } ] }`. 
    If the field is optional, add an `if` condition in the processor: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default", "if": "ctx.my_field != null" } } ] }`.

中文步骤

  1. Update the pipeline to include the required field in its definition: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default" } } ], "version": 1 }`.
  2. If the field is optional, add an `if` condition in the processor: `PUT _ingest/pipeline/my_pipeline { "processors": [ { "set": { "field": "my_field", "value": "default", "if": "ctx.my_field != null" } } ] }`.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    The pipeline definition still lacks the field declaration; the processor will fail again.

  2. 95% fail

    The configuration is identical; the error will persist.
