Description RamaKasturi 2020-09-09 13:10:53 UTC
Description of problem:
When running the command "oc logs -f dc/deployment" with 4.6/4.5 oc client it gives me the error "Error from server (BadRequest): converting (url.Values) to (v1.DeploymentLogOptions): unknown conversion"

Version-Release number of selected component (if applicable):
[ramakasturinarra@dhcp35-60 openshift-client-linux-4.6.0-0.nightly-2020-09-08-123737]$ ./oc version
Client Version: 4.6.0-0.nightly-2020-09-08-123737
Server Version: 4.6.0-0.nightly-2020-09-08-123737
Kubernetes Version: v1.19.0-rc.2+068702d

How reproducible:
Always

Steps to Reproduce:
1) install latest 4.6 cluster
2) Run the command oc create deploymentconfig my-nginx --image=nginx
3) Run the command oc logs -f dc/my-nginx

Actual results:
Below error is seen
Error from server (BadRequest): converting (url.Values) to (v1.DeploymentLogOptions): unknown conversion

Expected results:
Logs should be displayed.

Additional info:
Tried with 4.5 latest nightly, seeing similar results
[ramakasturinarra@dhcp35-60 openshift-client-linux-4.5.0-0.nightly-2020-09-08-123650]$ ./oc version
Client Version: 4.5.0-0.nightly-2020-09-08-123650
Server Version: 4.6.0-0.nightly-2020-09-08-123737
Kubernetes Version: v1.19.0-rc.2+068702d

custom deployments as well gives same error, steps to reproduce the same here:
==============================================================================
1) oc create -f https://raw.githubusercontent.com/openshift-qe/v3-testfiles/master/deployment/custom-recreate.yaml

2) Check the logs using the command oc  logs -f dc/<dc_name>

You will see the same error as mentioned in the Actual results.

Comment 2 Maciej Szulik 2020-09-09 18:50:56 UTC
I verified this with both oc 4.5 and 4.6 and I'm not seeing this happening. 
I'm going to close this, feel free to re-open and attach -v=9 with it as well.

Comment 4 RamaKasturi 2020-09-10 05:52:40 UTC
Also tried the same on a 4.5 cluster with 4.5 client and i see that it works and does not throw error as above

[ramakasturinarra@dhcp35-60 openshift-client-linux-4.5.0-0.nightly-2020-09-08-123650]$ ./oc logs -f dc/my-nginx
--> Scaling my-nginx-1 to 1
error: update acceptor rejected my-nginx-1: pods for rc 'test1/my-nginx-1' took longer than 600 seconds to become available

Comment 5 Maciej Szulik 2020-09-10 19:52:07 UTC
It's a bug in openshift-apiserver, PR on the way.

Verified with the payload below and i see that it works fine. Ran through auto script.

Based on the above moving the bug to verified state.
