bundle: command not found when running from cronjob on aws

Question

Running cronjob as root user in aws. ruby v 3.0, rails v 7.0.2.4.

The file that is created from running aws ebextension.

files:
  #The things to run inside cron task
  “/usr/local/bin/tasks.sh”:
    mode: “000755”
    owner: root
    group: root
    content: |
      #!/bin/bash
      if [ “$RAILS_ENV” = “production” ]
      then 
        cd /var/app/current
        bundle exec bin/rails runner -e production lib/device_proc.rb >> /tmp/log1.log 2>&1
      elif [ “$RAILS_ENV” = “staging” ]
      then
        cd /var/app/current
        bundle exec bin/rails runner -e staging lib/device_proc.rb >> /tmp/log2.log 2>&1
      fi

 #Run cron task every 5 minutes
 "/etc/cron.d/tk_cron":
   mode: "000644""
   owner: root
   group: root
   content: |
      0,5,10,15,20,25,30,35,40,45,50,55 * * * * root /usr/local/bin/tasks.sh

I am testing crontab in staging environment. I checked the created log file and it gives error

/usr/local/bin/tasks.sh: line 9: bundle: command not found

But if I run the command from aws session manager console, as root user, the command works. It is just that running from cronjob is throwing errors, despite that both are run as root user.

I tried running the bundle from my ruby installation path, /var/app/current/vendor/bundle/ruby/3.0.0/bin/bundle exec as been discussed in this question, but to no avail.
