Deployment error while using a http connector

@Kishore since you are using camunda springboot starters you need to register the connector plugin to the process engine plugins.

Refer this post to configure the Process Engine Plugin as Java config:

If you are using xml config then register the connector plugin as like:

<process-engine name="default">
    ...
    <plugins>
      <plugin>
        <class>org.camunda.connect.plugin.impl.ConnectProcessEnginePlugin</class>
      </plugin>
    </plugins>
Configure the Process Engine Plugin
