Re: Moving a mutated block gives error

[Beka Westberg]

Hello,

Thank you for providing the full text of your error! That is always really helpful for debugging :D

I found a match for your issue here, and it seems that there problem was that their mutation wasn't properly round-tripping through XML. Meaning their domToMutation function wasn't properly creating all of the fields/inputs of the original block.

If you need more help debugging from there, could you provide the full text of your block (including the mutation code)? If people here can pull your code and play with it, I'm sure someone can figure it out!

Best wishes,

Beka
