delete method does take agent version

Module: 00

Lab/Demo: 02

Fixes # .

@v-vfarias can you take a look at this? We need to lock versions of our packages for these labs to avoid changes like this, if you can test with the latest then lock our pip install. Likely need to lock the rest of the lab versions soon too

I'm not able to replicate this. @rob-foulkrod are you still seeing the issue? Are you running the code locally or in the cloud shell?

Learners were in cloudshell. I replicated it local to be sure.

@buzahid where did you see success, local or in cloudshell?

@rob-foulkrod you saw the same thing in both places, can you check the library version you have installed?

[v-vfarias]

During my testing, I have faced the same issue as @rob-foulkrod mentioned. Removing the argument works, but also checking that other labs has the same clean-up methods used but no errors are raised, verifying that at the moment.
