But When i tried to run custom functions like finding a max number.

if x > y:
        return x
    return  #y
def max_of_three( x, y, z ):
    return max_of_two( x, max_of_two( y, z ) )
print(max_of_three(3, 6, -5)) 

it gives a error

Error querying logs: Internal error - 502 Bad @Gateway%

Also when i try to check logs the same error reflecting

Answer 1

I have used custom functions in Python on Fission and they work fine. I followed this blog post as is and it worked without any issue.

Also, have you checked the following:

1. Check if the package build of your function has succeeded with fission pkg list
2. Check if your route is correct with fission route list
3. Check the logs of your router pod to see if the request got through
4. Use fission function test with --verbosity=2 to test your function locally, post your output here

I found these above steps mentioned for a similar error in their slack channel.
