uninitialized constant Dpl::Providers::Heroku::JSON (NameError)

[maiquelcraash]

Getting uninitialized constant Dpl::Providers::Heroku::JSON (NameError) error at the "Authenticate deployment" step for the Heroku DPL. This happens only when using Ruby 3 + the latest DPL version (v2.0.3-beta.5 and v2.0.4-beta).

Not sure this is related, but it seems that the json gem was removed from this DPL.
