Apache Solr : Error : unknown field _src_

Question

I went through this link and added the code in one of core to upload a multilevel JSON and it worked very well but when I created another core and added same then it is throwing the below error. I spent so much time to solve this error but no luck. The error is,

{
  "responseHeader":{
    "status":400,
    "QTime":93},
  "error":{
    "metadata":[
      "error-class","org.apache.solr.common.SolrException",
      "root-error-class","org.apache.solr.common.SolrException"],
    "msg":"ERROR: [doc=5b62d25] unknown field '_src_'",
    "code":400}}

I have added the below code in my solrconfig.xml file.

<initParams path="/update/json/docs">
  <lst name="defaults">
    <!-- this ensures that the entire JSON doc will be stored verbatim into one field -->
    <str name="srcField">_src_</str>
    <!-- This means a the uniqueKeyField will be extracted from the fields and
         all fields go into the 'df' field. In this config df is already configured to be 'text'
     -->
    <str name="mapUniqueKeyOnly">true</str>
    <!-- The default search field where all the values are indexed to -->
    <str name="df">text</str>
  </lst>
</initParams>

It means my entire JSON will be stored against the key src.

It might be the case that you are using the params.json file provided by the default configuration, even though you are using your own schema.xml file. Have a look at the core's conf folder and look for the params.json file. If you find it over there, comment it all out.
