Hi @Margaux

When does this error happen? Could you provide a sample workflow?
You could try downgrading your activity packs and making sure that you have access to all dependencies.

In case this is a process that runs correctly from Studio but not from Orchestrator, please copy the missing activity packages from your local folder to the one used by Orchestrator (please refer to the documentation for the paths).

Hi @loginerror,

I fixed it by rebuilding the faulty component. Do not know what caused the error, just hoping it wont come up again.


Hi @Margaux,
By ‘rebuilding faulty component’, what exactly did you mean?


Fixed this one for me as well. Just to be specific, I just had to recreate Main.xaml.


Yes just rebuild it by copying and pasting.
