flyctl launch validation error for region


When I run flyctl launch, at the step where I choose a region, I get this error:

? Select region: fra (Frankfurt, Germany)
Error Validation failed: Name may only contain numbers, lowercase letters and dashes

I got this using flyctl version 0.0.441. I also got the same when using versions 0.0.440, 0.0.430 and 0.0.410.

Any help would be appreciated :pray:

I found this comment on another thread, so I also tried to run it as flyctl launch --region=fra but it resulted in the same error message.

Sorry, I misattributed the error message to the region — the app name I was inputting had an underscore :person_facepalming:
