Starting with Resilio Connect 2.9 transfer of files from and to cloud storages directly is supported. A job may have object storage path configured for an Agent. However, once configured, it cannot be changed to a folder on local drive, or vice versa, by just editing the job. If done for an active job run, the error appears.
Resilio Connect Agent cannot switch the path when job is running.
The fix for Sync job is to remove the agent from the job, save it, add the agent with new path and save again. The fix for Distribution, Consolidation or Script jobs is to restart the run after editing the path.
