Сombine multiple SOLR fields into one

I have few dynamic Solr fields with similar pattern name (text_*) e.g. "text_1", "text_2", "text_3". I need to combine all such attributes into one multiValued attribute: ["text_1", "text_2", "text_3"] I have tried to use the next approach with pattern:

 <dynamicField name="text_*" type="string" stored="true"/>
 <dynamicField name="allTexts"  class="solr.StrField" sortMissingLast="true" docValues="true" multiValued="true" stored="true"/>
 <copyField source="text_*" dest="allTexts"/>

But it is not working as SOLR face with the ERROR:

 Can't load schema /opt/.../managed-schema: Dynamic field name 'allTexts' should have either a leading or a trailing asterisk, and no others.

Maybe there is some other approach how it is possible to combine dynamic fields into one multiValued field by field name Pattern?

You want to define a regular field, not a dynamic field (which is that you've typed).

A dynamic field requires a wildcard to be present somewhere in the name (since that's what a dynamic field is - it supports wildcard matching of field names).

Swap it out with

<field name="allTexts"  class="solr.StrField" sortMissingLast="true" docValues="true" multiValued="true" stored="true" />
