Thanks for the report! Could you run the following in a Rails console (`RAILS_ENV=production bundle exec rails c`)? ```ruby Account.find_local!('yourusername').user.applications.map { |app| app.scopes }.filter do |scopes| scopes.map { |scope| ScopeParser.new.parse(scope)...

Hm, strange, what about: ```ruby Account.find_local!('SubwayTooter').user.applications.map { |app| app.scopes }.filter do |scopes| scopes.map { |scope| ScopeTransformer.new.apply(ScopeParser.new.parse(scope)) } false rescue true end ```

```ruby Doorkeeper.config.application_model.authorized_for(Account.find_local!('SubwayTooter').user).map { |app| app.scopes }.filter do |scopes| scopes.map { |scope| ScopeTransformer.new.apply(ScopeParser.new.parse(scope)) } false rescue true end ```

```ruby Doorkeeper.config.application_model.authorized_for(Account.find_local!('SubwayTooter').user).filter do |app| app.scopes.map { |scope| ScopeTransformer.new.apply(ScopeParser.new.parse(scope)) } false rescue true end ``` (scrub the secrets if needed)

ok this appears to be a very old app record with broken scopes, we would need to make sure it's not currently possible to register such apps, and to handle...

What error did you get?

Thanks! 4.1.0 introduced scopes with underscores, but our parser does not handle that. Going to fix the issue!

I can't reproduce the issue, are you sure this is caused by an app with `read write follow` scopes? What is the exact backtrace? Are there apps with other scopes?
