Why getting "Sync Connector related error. Error deserializing link..." error

[Z1x2c3v4b5n6m7,8.9]

Not sure if this the appropriate place for raising the question.

I am trying to create a RTC attribute -> Jira attribute mapping using a RTC Sync tool.  On the RTC side, I have a Description attribute which is HTML  and, on the Jira side, I believe it is Wiki.  I am therefore using the following mapping (see the screen shot at the end).
On the RTC side, I have a work item, which has a URL in the description. This is apparently causing a mapping exception:
-----
"com.tasktop.internal.sync.core.SyncSubmissionException: Sync Connector related error. Error deserializing link: {“schema”:{“fields”:[{“id”:“location”,“label”:“URL”,“type”:“URI”,“template”:{“standardField”:“location”,“label”:“Location”},“required”:true,“readOnly”:true,“constraints”:{“absoluteUri”:true}}]},“attributes”:{“location”:“https://jsw.ibm.com/browse/DBACLD-10563?atlLinkOrigin\u003dc2xhY2staW50ZWdyYXRpb258aXNzdWU%3D”}}           at com.tasktop.internal.sync.core.SyncAdapter.putSyncItem(SyncAdapter.java:590)           at com.tasktop.internal.sync.core.state.UpdateProxyState.transition(UpdateProxyState.java:120)           at com.tasktop.internal.sync.core.state.SyncState.performTransition(SyncState.java:80)           at com.tasktop.internal.sync.core.WorkerJob.onPoll(WorkerJob.java:51)           at com.tasktop.server.core.ServerJob.run(ServerJob.java:90)           at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)"
…in which the value for the ‘location’ is the actual URL.Does anyone know why I am hitting this issue and how it can be resolved? (edited) 

See the screen shot in case it is going to be helpful
