I’m using Solr-9.0.0 with Docker on Windows, and I’m trying to index a simple document.

The first thing I did is creating a core using docker terminal

Then I’ve renamed managed-schema.xml to schema.xml then I’ve added one single line :

<field name="data_field" type="text_general" indexed="true" stored="true" required="true" multiValued="false" />

Then I’ve updated solrconfig.xml by adding this line

<schemaFactory class="ClassicIndexSchemaFactory"/>

And I’ve removed those lines from solrconfig.xml

<updateProcessor class="solr.UUIDUpdateProcessorFactory" name="uuid"/>
  <updateProcessor class="solr.RemoveBlankFieldUpdateProcessorFactory" name="remove-blank"/>
  <updateProcessor class="solr.FieldNameMutatingUpdateProcessorFactory" name="field-name-mutating">
    <str name="pattern">[^w-.]</str>
    <str name="replacement">_</str>
  </updateProcessor>
  <updateProcessor class="solr.ParseBooleanFieldUpdateProcessorFactory" name="parse-boolean"/>
  <updateProcessor class="solr.ParseLongFieldUpdateProcessorFactory" name="parse-long"/>
  <updateProcessor class="solr.ParseDoubleFieldUpdateProcessorFactory" name="parse-double"/>
  <updateProcessor class="solr.ParseDateFieldUpdateProcessorFactory" name="parse-date">
    <arr name="format">
      <str>yyyy-MM-dd['T'[HH:mm[:ss[.SSS]][z</str>
      <str>yyyy-MM-dd['T'[HH:mm[:ss[,SSS]][z</str>
      <str>yyyy-MM-dd HH:mm[:ss[.SSS]][z</str>
      <str>yyyy-MM-dd HH:mm[:ss[,SSS]][z</str>
      <str>[EEE, ]dd MMM yyyy HH:mm[:ss] z</str>
      <str>EEEE, dd-MMM-yy HH:mm:ss z</str>
      <str>EEE MMM ppd HH:mm:ss [z ]yyyy</str>
    </arr>
  </updateProcessor>
  <updateProcessor class="solr.AddSchemaFieldsUpdateProcessorFactory" name="add-schema-fields">
    <lst name="typeMapping">
      <str name="valueClass">java.lang.String</str>
      <str name="fieldType">text_general</str>
      <lst name="copyField">
        <str name="dest">*_str</str>
        <int name="maxChars">256</int>
      </lst>
      <!-- Use as default mapping instead of defaultFieldType -->
      <bool name="default">true</bool>
    </lst>
    <lst name="typeMapping">
      <str name="valueClass">java.lang.Boolean</str>
      <str name="fieldType">booleans</str>
    </lst>
    <lst name="typeMapping">
      <str name="valueClass">java.util.Date</str>
      <str name="fieldType">pdates</str>
    </lst>
    <lst name="typeMapping">
      <str name="valueClass">java.lang.Long</str>
      <str name="valueClass">java.lang.Integer</str>
      <str name="fieldType">plongs</str>
    </lst>
    <lst name="typeMapping">
      <str name="valueClass">java.lang.Number</str>
      <str name="fieldType">pdoubles</str>
    </lst>
  </updateProcessor>

  <!-- The update.autoCreateFields property can be turned to false to disable schemaless mode -->
  <updateRequestProcessorChain name="add-unknown-fields-to-the-schema" default="${update.autoCreateFields:true}"
           processor="uuid,remove-blank,field-name-mutating,parse-boolean,parse-long,parse-double,parse-date,add-schema-fields">
    <processor class="solr.LogUpdateProcessorFactory"/>
    <processor class="solr.DistributedUpdateProcessorFactory"/>
    <processor class="solr.RunUpdateProcessorFactory"/>
  </updateRequestProcessorChain>

Then I reloaded the core from the UI

Finally and using documents in the UI, I tried to index a docuement :

{
  "id":"test_id",
  "data_field":"test value to data field"
}

then I got the following error : Exception writing document id test_id to the index; possible analysis error.

I’ve tried with other types, string for example and it worked just fine, but I need it to be text_general
