it's a strongly worded warning, here's what the dev wrote when they added the log
Currently MM doesn't have a way to validate Mesh AP profiles as the effective Mesh Cluster profiles are not accessible on MM, they are only accessible on MD.
On MM add a warning when the user enters reprovision AP and the AP is targeted to be a mesh portal or point.
The warning should indicate that mesh provision will fail on LMS <> if the ap-group entered in reprovision doens't have mesh cluster profiles on the node where LMS is currently present.
The LMS IP, ap-group and node path of the LMS shall be displayed in the warning.
