Root Cause

A pipeline processor references a field that is not defined in the pipeline configuration, causing parse failure.

generic

中文

管道处理器引用了管道配置中未定义的字段，导致解析失败。

Workarounds

  1. 92% success Update the pipeline to define the missing field using the `set` processor with a default value: `PUT _ingest/pipeline/my_pipeline { "processors": [{"set": {"field": "my_field", "value": "default"}}] }`. 
    Update the pipeline to define the missing field using the `set` processor with a default value: `PUT _ingest/pipeline/my_pipeline { "processors": [{"set": {"field": "my_field", "value": "default"}}] }`.
  2. 88% success Remove the processor that requires the undefined field if it is not needed: `PUT _ingest/pipeline/my_pipeline { "processors": [] }`. 
    Remove the processor that requires the undefined field if it is not needed: `PUT _ingest/pipeline/my_pipeline { "processors": [] }`.
  3. 95% success Use the `_simulate` API to test the pipeline with sample documents before applying: `POST _ingest/pipeline/my_pipeline/_simulate { "docs": [{"_source": {"field": "test"}}] }`.

中文步骤

  1. 更新管道以使用 `set` 处理器定义缺失字段并设置默认值：`PUT _ingest/pipeline/my_pipeline { "processors": [{"set": {"field": "my_field", "value": "default"}}] }`。
  2. 如果不需要该处理器，则将其从管道配置中移除：`PUT _ingest/pipeline/my_pipeline { "processors": [] }`。
  3. 使用 `_simulate` API 在应用前测试管道：`POST _ingest/pipeline/my_pipeline/_simulate { "docs": [{"_source": {"field": "test"}}] }`。

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Field definition errors will persist unless the pipeline configuration is corrected properly.

  2. 95% fail

    Restarting does not fix configuration errors; the pipeline will still fail to parse.

  3. 85% fail

    The original pipeline remains broken and cannot be used for indexing.
