No dev packages

Any idea of what to do ?

Thanks

Hey @fohoizey, sorry for this issue. It seems to be a recurring issue with Atom packages, we'll look into it!

Same issue here.

Hello guys, I have an idea to solve this but I can't reproduce this error so I can't test it, could you help? Maybe by providing a MJML template where it happens.

A friend of mine tried reinstalling the package and it fixed it, can you try it to see if it solves the problem for you?

[JeffCleverley]

I had previously uninstalled the package. As I have just updated Atom and a few other packages, I figured I would try this again.

Unfortunately, I am getting no preview and no error message, sorry.

Thanks for the update, this might be an unrelated issue which would also mean this one is fixed by reinstalling the package/updating Atom, we'll figure it out!
