httpcache example is not working

[ghost]

Hi,

Hope you are all well !

I tried to run the httpcache example but it displays the following error:

  panic: runtime error: invalid memory address or nil pointer dereference
  [signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x91c62d]

  goroutine 1 [running]:
  github.com/devopsfaith/krakend/router/gin.ginRouter.Run(0xc000138c80, 0xf21998, 0x0, 0x0, 0xc000114ee0, 0xb1fd20, 0xc00010f580, 0xb2ed80, 0xc00010f520, 0x0, ...)
    /go/pkg/mod/github.com/devopsfaith/krakend@v1.1.1/router/gin/router.go:96 +0x3ad
  main.main()
    /app/main.go:56 +0x657

Is it possible to fix ? how to fix it ?

Thanks in advance for your insights or inputs on that topic.

Cheers, X

you're right. the examples from this repo are 2 years old and they use an older krakend release, not compatible with the current one.

we'll try to update the project in the next weeks

[ghost]

yeah, would be awesome to fix them. I managed to create a version with httpcache with diskv but your examples need a refresh.

Any chance to fix them today ? I need it for project ^^

[Mistic92]

I tried to use them today but failed too :)

[azubkokshe]

Please fix examples :((
