json_pure 2.7.4 breaks uaac

[MiliDurasovic]

Since json_pure version 2.7.4 I receive the following error while setting the target:

uaac --skip-ssl-validation  target https://uaa."${api}" -t
...
wrong number of arguments (given 2, expected 1)

Afterwards .uaac.yml is simply empty:

# cat ~/.uaac.yml
--- {}

After rolling back to json_pure version 2.7.2, uaac works again without any issues.

Maybe consider strictly pinning to json_pure 2.7.2 until the issue has been identified and resolved?

I'm experiencing this exact issue starting today...

Which version of CF-MGMT are you using @MiliDurasovic?

[jensdaseking]

Our workaround:

gem install cf-uaac
gem uninstall json_pure --all --force
gem install json_pure --version 2.7.2

[MiliDurasovic]

@CFMCGEE I´m not using cf-mgmt and I don´t think it matters for this issue.

We applied this workaround also in our docker images.

gem install cf-uaac
gem uninstall json_pure -aIx
gem install json_pure -v 2.7.2

hi,

for now you can use the workaround. there are multiple json libraries in use which cause the problem, e.g. ruby/json#646

Will cleanup here but first in cloudfoundry/cf-uaa-lib#95

@MiliDurasovic - Apologizes, I meant UAAC CLI. I'll try the work around provided. Thanks for raising this issue!

[strehle]

@MiliDurasovic heads up: please check if with https://github.com/ruby/json/releases/tag/v2.7.5 the issue is fixed ? because changelog seems to show this.

However there will be a cleanup and only one json library will be initialized in future

[MiliDurasovic]

@strehle Thank you.
I can confirm that the issue is gone for me with https://github.com/ruby/json/releases/tag/v2.7.5 .

[CFMCGEE]

@strehle Thanks! Works for me now as well.

@strehle Since tonight we suddenly receive another error:

+ uaac --skip-ssl-validation target https://uaa."${api}"

Looks like the removal of multi_json is the cause:
cloudfoundry/cf-uaa-lib#95

[strehle]

see https://github.com/cloudfoundry/cf-uaa-lib/releases/tag/v4.0.6

Sorry for breaking it. Will do replacement in several steps, but we want remove this library and replace it with json / json_pure only
