Deployment deferred awaiting probe deployment or redeployment: (1) error, Received status (1) on response (for sendRcv) for cmd = 'probe_config_set'
Release : 9.2.0
Component : UIM - ROBOT
The robots for the devices were all at 9.20 at various levels of hotfixes.
Checking the version of the attr_publisher that was installed (Controller GUI -> Status -> Installed packages) it was observed that the version of attr_publisher installed was 7.97.
attr_publisher 7.97 was compiled with vs2008 which is incompatible with Robot 9.20 which was compiled with vs2017.
attr_publisher 9.20 has been compiled with vs2017 and is required for Robot 9.2x
Download and manually deploy attr_publisher 9.20 to the 9.2x robots.
With UIM 20.1, the robot version is 9.30 and the required version of attr_publisher (9.30) is delivered with the 20.1 upgrade/install.
