Solr Collection is not accepting Date datatype

Hi friends,

After adding my field tags in the schema.xml file like below

<field name="_version_" type="plong" indexed="true" stored="true" multiValued="false" />
<field name="id" type="string" indexed="true" stored="true" required="true" multiValued="false" />
<field name="ip" type="text_general" indexed="true" stored="true"/>
<field name="request_date" type="date" indexed="true" stored="true"/>
<field name="request" type="text_general" indexed="true" stored="true"/>
<field name="department" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="category" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="product" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="action" type="string" indexed="true" stored="true" multiValued="false"/>

And when i tried to create solr collection it is returning error like below

Unable to create core [live_logs15_shard1_replica_n1] Caused by: Unknown fieldType 'date' specified on field request_date"}}

It is not accepting date datatype that i specified. Suppose instead of date datatype if i specify string for the field request_date means, then i can create collection successfully, but the solr collection is not accepting date data type and not sure the reason besides this issue.

Thanks in advance.
