slack_notify script in shared-lib not working for some pipelines

[vj4a]

Hello @santhosh-tg , @gandham-santhosh ,

In some pipelines like ArtifactUpload/Core/Assessment: , slack_notify stage is passing as expected irrespective of whether required environment variables is passed or not but in some like ArtifactUpload/Core/AdminUtils, it gives the below exception,

Org.jenkinsci.plugins.workflow.actions.ErrorAction$ErrorId: 8a11b382-45fd-4cdc-a70e-2e9c05661929
hudson.remoting.ProxyException: org.codehaus.groovy.runtime.typehandling.GroovyCastException: Cannot cast object '' with class 'java.lang.String' to class 'int'

We have tried the shared-lib present in the repo dicdiksha/sunbird-devops where it looks like it has been fixed with this commit but we are still facing the same error.

We'll look into the same. Kindly let us know if there is any fix already available.

Thanks

Hi @vj4a We haven't faced this issue before. Even with recent Installation at OCI we didn't have this issue.

It might be related to the Jenkins upgrade / plugins version but not sure though. You may want debug further to confirm.

Not yet @gandham-santhosh , we are checking on it.

Except for Artifact Uploads/Core/AdminUtils, all the other notify errors are pertinent to uploads to the storage bucket and not container registry which is a pattern we have observed.

To rule out whether this is due to Jenkins latest version, we'll test that too.
We'll update here once we have a fix for it.

I don't know whether it will work - but just my guess

when enter the function

def call(String buildStatus, String release_tag=null, String jobName=null, int buildNumber=0, String jobUrl=null)

buildNumber is an integer, with 0 as default if whoever calling it does not provide the value

in this line

 if (buildNumber == 0)

we are doing integer comparison. In fact, if true

buildNumber = env.BUILD_NUMBER

while all env.* are actually string - error happens when no values is pass to the function OR the passed value is a 0

things you can try - (it is groovy, not sure how that works in jenkins) do a def or a int, in the very begining - either

def myBuildNumber = env.BUILD_NUMBER.toInteger()

or

int myBuildNumber = env.BUILD_NUMBER

this is a bit different because the cast happened even before an if then, it is in the declaration/definition - again, those code are groovy - I haven't tried inside jenkins. If this dec/def works, you should be able to do

                if (buildNumber == 0)
                    buildNumber = myBuildNumber 

where myBuildNumber is an integer - so that integer to integer assignment should NOT throw error

or maybe just

                if (buildNumber == 0)
                    buildNumber = env.BUILD_NUMBER.toInteger()

if it is supported in grovvy in jenkins

@heungheung , Thanks for the info, the typecasting was the issue. Also, in artifact upload to storage buckets, the build number is null which is to be checked further. For now, this is a workaround for the exception.

                if (buildNumber == 0)
                    env.BUILD_NUMBER = env.BUILD_NUMBER == "" ? "0" : env.BUILD_NUMBER
                    buildNumber = env.BUILD_NUMBER.toInteger()
