Hi,
I am getting this error with the configuration below:

Error:

lib/ruby/gems/2.7.0/gems/fluent-plugin-sentry-http-0.1.1/lib/fluent/plugin/in_sentry_http.rb:4:in `<module:Fluent>': uninitialized constant Fluent::HttpInput (NameError)
 Did you mean?  HTTPClient

Configuration:

  @type sentry_http
  port 80
  bind 192.168.50.45
  # <project 999>
  #   tag sentry.egg
  #   key 123
  #   secret 123
  # </project>
</source>
