I have a ruby/thor script that uses savon to make a soap request. If I run the script on my desktop with:

thor my_script:my_action

everything works fine. If I run the script with:

bundle exec thor my_script:my_action

I get an error when savon tries to parse the respones. The error is:

Zlib::DataError incorrect header check

I used Gem.loaded_specs.values.map {|x| "#{x.name} #{x.version}"} to see which versions of gems were loaded. with or without the bundle exec the versions are the same. bundle exec does include 2 extra gems bundler and io-console.

If I run the same script on a Server 2012 box I get the Zlib error with or without bundle exec.

How can I get more information on how to make this work?

Desktop Ruby: ruby 2.3.1p112 (2016-04-26 revision 54768) [x64-mingw32]

Server Ruby: ruby 2.3.3p222 (2016-11-21 revision 56859) [x64-mingw32]

  • Pleae add the stacktrace too – kiddorails Aug 18 '17 at 20:28
  • It appears there could be a bug in the http lib. See: https://bugs.ruby-lang.org/issues/11268 . I looked at 2.3.4 and it's not fixed even there. You can find the patch file here: https://bugs.ruby-lang.org/attachments/5489/net_http.patch . You only need to change one line in `lib/net/http/generic_request.rb` and one line in `response.rb`. – Casper Aug 18 '17 at 20:55
  • Alternative fix in the client code instead: https://stackoverflow.com/questions/37926803/why-am-i-getting-zlibdataerror – Casper Aug 18 '17 at 20:58
