Installation problems

[tednought]

I am having trouble installing the code on a CloudShell environment. When I try to run either cdk deploy or python3 app.py, it returns the following:

jsii.errors.JavaScriptError:
   Error: Cannot find asset at /home/cloudshell-user/lambda
The above exception was the direct cause of the following exception:
   RuntimeError: Cannot find asset at /home/cloudshell-user/lambda

(In each case, I'm leaving out a string of lines which presumably identify the steps leading up to the attempt to access the unfindable asset.)

If I try to run python3 newrecord.py, it says
Dyndns stack not found, ensure the right AWS CLI profile is being used.

Any idea what's going on, or what I should be doing differently?

If it's relevant, the shell kept throwing up errors (of the "no-such-file-exists" variety) when I tried to install after cloning the github repository. I was able to get the libraries installed and the code to run, up to the errors described above, by uploading each of the relevant files into the shell using the "actions" tab.

Thanks in advance for any help.
