[YANGTOOLS-324] NullPointerException in AbstractImmutableNormalizedValueAttrNode causes flow-programming failure

Blocks — Sun, 10 Apr 2022 18:35:20 +0000

am seeing the following exception during flow-programming.
From the trace-back, it is not clear if there is an error in match/action structure. Hence am not sure where the bug should belong to.

Filing it as yangtools bug for now since the cause is originating from there.
Happy to move back to ovsdb if there is an issue in the usage.
