When I try to unbind a specific SendGrid service from my Java Liberty application running on Bluemix, I get the following error message:
Service broker error: {"description"=>"Received exception with class 'javax.ws.rs.client.ResponseProcessingException' and message 'Problem with reading the data, class com.appdirect.backend.integration.custom.sendgrid.output.SendGridResult, ContentType: application/xml;charset=utf-8.' while calling integration endpoint 'null'."}
I get the same message using the Bluemix gui and cf cli.
