res._removedHeader does not exists

See original GitHub issue

I got this error:

TypeError: Cannot set property 'content-length' of undefined
    at ServerResponse.OutgoingMessage.removeHeader (_http_outgoing.js:388:30)
    at ServerResponse.onResponseHeaders (/home/imbolc/0/p/action-loop/node_modules/compression/index.js:202:13)
    at ServerResponse.writeHead (/home/imbolc/0/p/action-loop/node_modules/on-headers/index.js:46:16)

    at process._tickDomainCallback (internal/process/next_tick.js:129:7)

I just fix this with monkey patching of compression/index.js:

      // header fields                                                                                                        
      res.setHeader('Content-Encoding', method)                                                                               
      try {                                                                                                                   
        res.removeHeader('Content-Length')                                                                                    
      } catch (e) {                                                                                                           
        console.log(e)                                                                                                        
        if (res._removedHeader === undefined) {                                                                               
          res._removedHeader = {};                                                                                            
        }                                                                                                                     
        res.removeHeader('Content-Length')                                                                                    
      }

Do you have any ideas why does it happen and what the right way to fix this?

Ah, thanks for the heads-up, @gr2m ! I see that PR was merged as well. It sounds like I can close this issue. Let me know if I should re-open for any reason 😃

this is not a compression issue, sorry for the noise 😃 I resolved the problem that Hoodie had via https://github.com/hoodiehq/hoodie-store-server/pull/60

Thanks for your great work, @dougwilson 👋 I think we can close this issue
