Did you have already a look at [this](https://juliadiff.org/ChainRulesCore.jl/stable/writing_good_rules.html#Patterns-that-need-rules-in-%5BZygote.jl%5D(https://github.com/FluxML/Zygote.jl)) or [this](https://github.com/rakeshvar/Zygote-Mutating-Arrays-WorkAround.jl)?

Btw. [Quoting the code](https://discourse.julialang.org/t/please-read-make-it-easier-to-help-you/14757) would help the reader of your post 🙂
