irshadshalu opened this issue · 1 comments
Description
I was trying to get Fn working on a Oracle Linux Server release 7.6 and followed the instructions in here . However when I invoke the function created with fn invoke myapp hello, It fails and throws a 500 Error message :
Error invoking function. status: 500 message: internal server error
Steps to reproduce the issue:
- Get a fresh Oracle Linux 7.6 Machine
- Install docker and it's dependencies
- Install and run Fn by following instructions at https://github.com/fnproject/fn#install-cli-tool\
Describe the results you received:
Fn invoke fails with error:
Error invoking function. status: 500 message: internal server error
Describe the results you expected:
That function should be invoked and working properly

I checked the logs of fn docker container and found this to be the cause:
