global:translateText permission error for Base Google NMT in v3beta1 API

[Erik Chan]

I am following the documentation on this page to use the base Google NMT in the v3beta1 API: https://cloud.google.com/translate/docs/translating-text-v3

curl -X POST \
     -H "Authorization: Bearer "$(gcloud auth application-default print-access-token) \
     -H 'Content-Type: application/json' --data "{
     model: 'projects/
     model: 'projects/project-id/locations/global/models/general/base',
     source_language_code: 'en',
     target_language_code: 'de',
     contents: ['Come here!']
}"

I don't receive permission errors with Custom Models but I am receiving a permission error with the Base NMT Model:

{"error"=>{"code"=>403, "message"=>"Cloud IAM permission 'cloudtranslate.generalModels.predict' denied. ", "status"=>"PERMISSION_DENIED"}}{"error"=>{"code"=>403, "message"=>"Cloud IAM permission 'cloudtranslate.generalModels.predict' denied. ", "status"=>"PERMISSION_DENIED"}}{"error"=>{"code"=>403, "message"=>"Cloud IAM permission 'cloudtranslate.generalModels.predict' denied. ", "status"=>"PERMISSION_DENIED"}}  Rendering models/translate_user.js.erb

Resolved, new IAM permissions were required (different than AutoML roles)
