Hi, I have an requirement in which I have to add some fields in schema at run time and after that i need to add the copy fields for some of the schema fields.
To add the fields in schema I used the following REST API, which is giving success response in output as shown below: *Post URL: *http://localhost:8080/solr/bookindex/schema/fields *Content-type :* application/json *Post Data :* [ { "indexed": "true", "name": "age", "stored": "true", "type": "long" }, { "indexed": "true", "name": "sex", "stored": "true", "type": "string" }, { "indexed": "true", "name": "_all", "stored": "true", "type": "string", "multiValued" : "true" } ] *Output Response :* { "responseHeader":{ "status":0, "QTime":202 } } After adding these fields in schema, as I executing the second call to add the copy fields in schema, i am getting an error *"Error persisting managed schema at /configs/myconf/managed-schema" *in response. Following are the details about REST API which i am using to add the copy fields along with error response. *Post URL: *http://localhost:7070/solr/bookindex/schema/copyfields *Content-type : *application/json *Post Data : * [ { "source":"age", "dest": "_all" }, { "source":"sex", "dest": "_all" } ] *Output Response :* { "responseHeader":{ "status":500, "QTime":190}, "error":{ "msg":"Error persisting managed schema at /configs/myconf/managed-schema", "trace":"org.apache.solr.common.SolrException: Error persisting managed schema at /configs/myconf/managed-schema\n\tat
