Hello all,
I have a problem with setting leaf-list during phase0 of schema upgrade.
Executing the following line after phase0, before phase1
maapi_set_elem2(ms, th, "3 4", "/servers-new/little-list");
result in:
TRACE MAAPI_SET_ELEM2 /servers-new/little-listDEBUG internal error -
--> CONFD_ERR

I realize that solving this could take time and unless I’ve done something obviously stupid please share your ideas to workaround this problem.
