Creating URLs with proper tools looks like this:

def builder = new URIBuilder(env.BUILD_URL)
def url = builder
    .setPathSegments(builder.getPathSegments() + ['api', 'json'])
    .setParameter('tree', 'actions[nodes[iconColor,running,displayName,id,parents]]')
    .toString()

and actually produces incorrectly-formatted URLs, e.g.
https://kibana-ci.elastic.co/job/elastic+kibana+pipeline-pull-request/34782//api/json?tree=actions%5Bnodes%5BiconColor%2Crunning%2CdisplayName%2Cid%2Cparents%5D%5D

(notice the double //)

def responseRaw = httpRequest([ method: "GET", url: url ])
def response = toJSON(responseRaw)

def graphAction = response?.actions?.find { it._class == "org.jenkinsci.plugins.workflow.job.views.FlowGraphAction" }

return graphAction?.nodes
}

def getFailedSteps() {
def steps = getSteps()
def failedSteps = steps?.findAll { it.iconColor == "red" && it._class == "org.jenkinsci.plugins.workflow.cps.nodes.StepAtomNode" }
failedSteps.each { step ->
step.logs = "${env.BUILD_URL}execution/node/${step.id}/log".toString()
}

return failedSteps
}
