Error Null Value: path1

My migration was about 6k work items deep when its hit this error:

[00:13:25 ERR] [v15.0.2] Could not save migrated work item 258259, an exception occurred.
System.AggregateException: One or more errors occurred. ---> System.ArgumentNullException: Value cannot be null.

Which seems to be work item specific because if I restart it fails on the same work item but I am unsure what would be causing this. The area and iteration path both exist in the target and are valid, not sure what else to check based on the error. Has anyone seen this one before?

@muradjames I will look into this and see if I have a similar case, let me know if you find any solutions

[MrHinsh]

@muradjames it looks like a bunch of things have been copied and pasted into the new config format that are invalid. Can you try with the latest version of the tool and using devopsmigration init to create a new config and then use the options provided.

[MrHinsh]

@muradjames nope... wait one! Its a bug in the code....

[MrHinsh]

Changes incoming #2004

[muradjames]

Thanks! But also my config is a disaster, it's true 😂

[MrHinsh]

I have exactly the same problem, except I have tons of configs to clean up.... :)

I really need a config builder!
