我有一个Rails 5 api-only应用程序。一切，身份验证以及发布和获取路径都一直有效，但是突然，我收到了此错误
ActionDispatch::Http::Parameters::ParseError (743: unexpected token at ''):
我回到了以前的版本，仍然遇到相同的错误。
我什至不知道从哪里开始寻找。这是跟踪：
(0.5ms) SELECT "schema_migrations"."version" FROM "schema_migrations" ORDER BY "schema_migrations"."version" ASC
↳ /Users/dariusgoore/.rvm/gems/ruby-2.4.1/gems/activerecord-5.2.3/lib/active_record/log_subscriber.rb:98
Error occurred while parsing request parameters.
