Unable to proceed with Chef Infra course on learn.chef.io

[ChaithraM]

I am a beginner and new to Chef and Docker. I was taking the Manage Your Fleet with Chef Infra course and I am stuck. I installed Docker and got it running. Opening the bash window seems to work fine as I get the following:
Agent pid 323
Identity added: .ssh/try-chef.key (.ssh/try-chef.key)

When I issue the command "chef-run web1 file hello.txt" which is the next step (https://learn.chef.io/courses/course-v1:chef+Infra101+perpetual/courseware/49dd59ea8b1f4c50ae9a260db35452ad/ad9c0599d525467b92fb0c6e52a025ba/) I get the following:

[✔] Packaging cookbook... done!
[✔] Generating local policyfile... exporting... done!
[✖] Applying file[hello.txt] from resource to target.
└── [✖] [web1] Failed to converge file[hello.txt].

Could not determine reason for converge failure.

An error occurred while converging the remote host.
I was unable to retrieve the log file which would allow
me to provide more information.  Here's where I looked:

  /var/chef-workstation/cache/run-report.json

I am using Mac OS 10.15. Chef Workstation Version installed is 21.4.365

I found this link https://discourse.chef.io/t/stuck-in-learn-chef-rally/14345 but this did not help me solve the issue.
Please help!

This is a known issue in the learn chef modules, we're working on prioritizing these updates with the docs team.
