Everything looks right on my end, but I’m getting a validation error after following all the steps. Is there a known issue with this right now, or a specific field that’s usually the culprit?
What’s the error? Also, what does your pipeline look like?

I see you’ve installed java, but what does your pipeline look like? Please use a code block to post it here.
pipeline {
agent {
label 'stapp01'
}
parameters {
string(name: 'BRANCH', defaultValue: 'master', description: 'Branch to deploy (master or feature)')
}
stages {
stage('Deploy') {
steps {
script {
if (params.BRANCH == 'master' || params.BRANCH == 'feature') {
withCredentials([usernamePassword(credentialsId: 'sarah', usernameVariable: 'USER', passwordVariable: 'PASS')]) {
sh """
git clone -b ${params.BRANCH} https://3000-port-vm53lq7spqfap5pu.labs.kodekloud.com/sarah/web_app.git /tmp/web_app
echo "$PASS" | sudo -S cp -r /tmp/web_app/* /var/www/html/
echo "$PASS" | sudo -S rm -rf /tmp/web_app
ls -la /var/www/html
"""
}
} else {
error "Invalid branch value: ${params.BRANCH}. Must be 'master' or 'feature'."
}
}
}
}
}
}
My main comment is that the first general step of this lab is to create a Jenkins node that runs as user sarah. So a lot of your pipeline is redundant – you don’t need to mess with credentials in the pipeline, since all of the relevant directories to the pipeline are owned by user sarah. So you can write a working pipeline that simply sets the current branch with git, and then does a git pull. This should suffice to pass Day 78.
Got it! After many attempts, I was finally accepted. Thanks @rob_kodekloud , can I share the script here?
Sure. I’m guessing it’s a lot simpler than your original draft 
Exactly 
pipeline {
agent { label 'stapp01' }
parameters {
choice(
name: 'BRANCH',
choices: ['master', 'feature'],
description: 'Select the branch to deploy'
)
}
stages {
stage('Deploy') {
steps {
sh """
cd /var/www/html
git fetch --all
git reset --hard
git clean -fd
git switch ${params.BRANCH}
git pull origin ${params.BRANCH}
"""
}
}
}
}
