iApp deployment - unexpected argument error

Hi All,

I am struggling with iApp deployment issue. Custom iApp has been developed and has been deployed many times to F5 BIG-IP devices. During iApp implementation phase iApp creates node object using the following command:

iapp::conf ltm node .....

For some reason I am not able to deploy it to one of the devices, I get error "node" unexpected argument....

It is a very typical deployment, verified license, TMOS version is 14.0.1.2, device F5 BIG-IP i2600.

I thought it's privileges issue, but Iapp has been deployed using admin account with full Admin rights.

Have you ever seen similar issue?
