"panic: reflect: call of reflect.Append on ptr Value" during hydrateProperty #3

Open raoel opened 3 years ago

raoel commented 3 years ago

It looks like it cannot hydrate the following property, when I run it in a debugger that is the property being handled.

I just started with Golang, I already tried to fix it but I can't :-/ I guess it's the hash "#" ?

stack:

Thanks for you patience, I totally forgot your issue. I'll try to reproduce and get back to you this week.

dolanor commented 3 years ago

Sorry it took so long, been quite busy. I found out that you're right, the problem is with the CATEGORIES, but not because of the #. It's the whole underlying type which doesn't hydrate correctly. the CONTACT is of the same type (type.CSV) and fails the same. I'm gonna try and fix it and update this issue when it's done.
