Pipeline failure in gctsDeploy

[Karan_Chopra_]

Hi Experts

I am trying to run pipeline for ABAP Development and Testing Process Using Git-Enabled Change and Transport System following the scenerio https://www.project-piper.io/scenarios/gCTS_Scenario/ on project piper but I am facing issue in gctsDeploy step where the Host is read.

step execution failed - cannot parse HTTP response with value <nil>

Below is the part of Jenkinfile and error

We faced a similar issue where the root cause was HTTPS connection to host system with no valid certificate. You can try to add skipSSLVerification: true in your deploy step config.

Hi Karin

As we do not have test system ready yet so we are trying to achieve the scenario in same system only, so that later on it will be easier and quick.

Yes I am passing our ABAP system URL onlyin the format HOST = <https://<host of the ABAP system>:<port>> , just for security reason I changed it here.

I have tried both the scenario (Set up a Pipeline-Based ABAP Development and Testing Process Using Git-Enabled Change and Transport ... - Single Jenkinfile with enviorent variables included) and OPEN SAP scenario in Devops with ABAP where we have separate config.yml, but unfortunately in both the cases I get this same error.

I tried with Getting Started With Project "Piper" - Project "Piper": Continuous Delivery for the SAP Ecosystem (p... , this is working fine and app gets deployed in BTP, so problem does not seems to be in Jenkins Server setting.

Hi Karan,

you can also start a pipline for the same system as you are developing - I am just not sure that I get the point, why you need to deploy again. Nevertheless, this should not be the issue.

But in your jenkinsfile, in the environment definition, I found this.

HOST = 'host'

What is this expected to achieve? You would need to define the URL to the ABAP system as HOST to allow Jenkins to start the respective action on that system and to pass over credentials

Kind regards

Hello Karin,

No I do not use config.yml in this case, but yes I have not added any colaborator also.

I will try that and see if it works , thankyou.

[Karin]

Hi,

do you also use a config.yml? If yes, then this issue comes up if indentations in the yml are not correct.

If not: is the user 'ABAP' that you use for democredentials a collaborator for the repository?

Kind regards

Karin

hi Karin

Even after adding colaaborator we get same error, we are not triggering pieline via transport release but directly from Jenikins Server. Also we do not have 2 systems so we are using one system only , could that be the reason for error as same system is given in pipeline?
