Jenkins Pipeline failed - jenkins

Question

I am running a scripted version of the Jenkins pipeline. It ran through all the stages except the last stage. It failed every time.
Here is the Jenkins code that keep on failing:
stage('Deploy Production') {
echo "Deploy Prod on: ${env.BRANCH_NAME}"
try {
if (env.BRANCH_NAME == 'master'){
withCredentials([[$class: 'UsernamePasswordMultiBinding', credentialsId: 'XX',
usernameVariable: 'XXXXX', passwordVariable: 'XXXXXX']]) {
sh 'npm run build-prod-ci'
sh 'cf login -u ${XXXXX} -p ${XXXXXX} -a website.com -o XXX -s XXXX'
sh 'cf blue-green-deploy Dashboard'
sh 'cf delete Dashboard-old -f'
}
}
} finally {
deleteDir()
sh 'cf logout'
}
}
This is the printout and the error message. Any help in resolving this issue is appreciated.
Plugin blue-green-deploy 1.3.0 successfully installed.

Previous stages with npm commands worked fine. Here is an example of a stage that worked:
stage('Run project tests and build') {
echo "Run project tests and build on: ${env.BRANCH_NAME}"
sh "npm run lint"
//sh "npm run compodoc-ci"
//sh "npm run test-coverage"
sh "npm run build-dev-ci"
}

This issue was self inflicted, and the comments that was given above gave me some hints to arrive at the solution.
The problem was that I was moving the original Jenkins code (I think it's called Declarative Pipeline) over to this form (scripted pipeline?), and I converted the code below without thinking because Jenkins is not something I work with everyday...
steps {
when {
branch 'dev'
}
}
post {
always {
deleteDir()
to
try {
if (env.BRANCH_NAME == 'dev'){
} finally {
deleteDir()
Anyway, the command deleteDir() delete the directory, and therefore it can't find that file anymore.
Thanks for the help guys. Much appreciated.
Lesson: check your code to understand what's it's doing. Copy and paste will only help to a certain extent.
