We have created an issue in Pivotal Tracker to manage this:

The labels on this github issue will be updated when the story is started.

Anybody looking into this? We would also like to use uaac in a Ruby 3 environment.

I also ran into this again. Ruby 3.0.0 has been out for 5 months. Please fix.

[LittleBaiBai]

Any update on this? We also ran into this and it has made troubleshooting harder than before.

Same here since we updated our docker images to Alpine 3.15 (with Ruby 3.0).

Thanks for the fix @strehle / @bgandon!

I'm still seeing an issue though with uaac target <hostname> --skip-ssl-validation:

$ uaac target uaa.sys.sprintred.cf-app.com --skip-ssl-validation
Unknown key: Max-Age = 86400

Target: https://uaa.sys.<domain>
$ uaac target uaa.sys.<domain>

Target: https://uaa.sys.<domain>

This is occurring on ruby 2.7.4, and ruby 3.1.0 with cf-uaac 4.4.0. Any ideas?

[geofffranks]

Actually, on ruby 3.1.0, even without --skip-ssl-validation, i get failures still:

uaac target uaa.sys.<domain>
Unknown key: Max-Age = 86400
failed to access https://uaa.sys.<domain>: tried to create Proc object without a block

[strehle]

@geofffranks can you please check your cf-uaa-lib and cf-uaac versions with gem, because I have tested this with ruby 3.1.x ( ruby 3.1.0p0 (2021-12-25 revision fb4df44d16) [x86_64-linux] ) and for me it worked, e.g.

uaac target https://login.uaa-acceptance.cf-app.com --skip-ssl-validation or other target with token request received one

check gem e.g. gem list |grep cf- cf-uaa-lib (3.14.4) cf-uaac (4.4.0)

if you have more version, please uninstall older versions, e.g. gem uninstall cf-uaa-lib and re-install latest cf-uaa-lib and cf-uaac

[geofffranks]

I only have cf-uaa-lib 3.14.4 and cf-uaac 4.4.0 as well. I did notice on ruby 3.1.0, if there was a nexisting uaac.yml, uaac target works, but other commands do not. Once deleting uaac.yml, target fails again on 3.1.0:

[strehle]

sorry, but I did not see it. I see it, if I enforce "gem install cf-uaac -v 4.3.0" on runtime > 3.x

I tested now in matrix with 2.7.4 , 3.0.0, 3.1.0

-> gem install cf-uaa-lib -> gem install cf-uaac

I tested with rvm on a ubuntu 20.x native and on my WSL 2 with ubuntu 18.04. With rvm I had to install (and compile) always cf-uaa* newly but I get it working with and without .uaac.yml.

I can reproduce what you write, but only with the mixed versions.

I am no expert if rvm or rbenv is better, e.g. https://metova.com/choosing-a-ruby-version-management-tool-rbenv-vs-rvm/ However , I cannot see it, and therefore dont really can do any fix. For CI there is github action with tests on all runtimes we mentioned, https://github.com/cloudfoundry/cf-uaac/actions

@bgandon any hints from your side ?

[geofffranks]

Well, I repaved my workstation and everything seems to be working now (it had been built with 4.3.0/3.14.3 and upgraded). I have no idea what rbenv/gem install did to me that made it all blow up, but thanks for taking a look!
