Steve Rowe commented on SOLR-8607:
----------------------------------
This workaround allowed me to create the {{new_txt}} field: first delete the
matching dynamic field, then add the new field, then re-add the deleted dynamic
field, all in one request:
{noformat}
$ curl -X POST -H "Content-type:application/json" --data-binary '{
"delete-dynamic-field":{"name":"*_txt"},
"add-field":
{"name":"new_txt","type":"string","indexed":"true","stored":"true"},
"add-dynamic-field":{"name":"*_txt", "type":"text_general", "indexed":true,
"stored":true}}' \
http://localhost:8983/solr/gettingstarted/schema
{"responseHeader": {"status":0, "QTime":81}}
$ curl http://localhost:8983/solr/gettingstarted/schema
[...]
"fields":[...{"name":"new_txt", "type":"string", "indexed":true,"stored":true}],
[...]
"dynamicFields":[...,{"name":"*_txt", "type":"text_general", "indexed":true,
"stored":true},
[...]

> Issue Type: Bug
> Components: Schema and Analysis
> Affects Versions: 5.3.1
> Reporter: kiran
> Priority: Minor

> If the all catch dynamic field '*' is present in a managed schema collection,
> then any field creation requests through Schema API return the
> confusing/weird error "Field $\{FIELD_NAME\} already exists".

> {code}
> The field 'userId' does not exist in the schema but it is also not possible
> to add this field because of the dynamic field '*'.
> While one should never define dynamic field '*' in a managed schema, the
> Schema API should atleast return some useful error message.
