Topic: WEIRD GENERATED TYPE NAME error

Thomas Welter (Oct 08 2024 at 19:26):

Hello all, I am exploring Roc but I quickly got stumped by an error. Not sure if this is a problem on my side or some kind of buggy build.

• I am running Roc through WSL
• rov version = roc nightly pre-release, built from commit 070d14a on Sa 13 Jul 2024 09:01:39 UTC
• copied the first "I'm a Roc application!" basic-cli example in the tutorial to a file main.roc
• error: WEIRD GENERATED TYPE NAME in ...lmYWNYOxnvo8r6YABXD-45UOw/PlatformTasks.roc
• (an arrow pointing to the end of imports [])
• I am expecting a type name next, like Effect. Type names must start with an uppercase letter.
• running with roc dev

What am I doing wrong?

@Thomas Welter that's an old version of Roc that was before we implemented buildin Tasks

Can you upgrade to a later version and let us know if that fixes the issue?

Thomas Welter (Oct 08 2024 at 20:24):

Woops I see now. I downloaded Roc a while ago and autocompleted to the old version today. It seems to work now!
Thank you Sam!
