[YANGTOOLS-285] full yang-ext:mount fails due to sub-modules

Sun, 10 Apr 2022 18:35:17 +0000

a full config or operational yang-ext:mount on a device with lots of modules/submodules is failing. It seems that the issue is in submodules.

Logs attached.

smaller chunks of the config/operational tree work fine.

in the config case I see logs on the CLI which get dropped from the logfile:

this one also gives an HTTP500:
