This is not datascience specific. I think the error is we're using '. ' instead of source, although from this
https://github.com/Microsoft/vscode-python/blob/b741e1af6d53cdf94765a6708964d489bd558ff8/src/client/interpreter/activation/service.ts#L105

It looks like it was on purpose.

Building the latest extension version from github master, activation errors still persist with conda.

Basically, before a recent PR (#5516, #4402), I think it was trying to do something like this, which is wrong:

$ <ENV>/activate

Error: activate must be sourced. Run 'source activate envname'
instead of 'activate envname'.

Now it's trying to do something like this (but it's also still wrong!):

$ source <ENV>/bin/activate

Error: no environment provided.

It should be either this:

$ source <ENV>/bin/activate <ENV>

Or, as a matter of fact, conda guys officially suggest using conda activate and conda deactivate instead of sourcing things manually: https://docs.conda.io/projects/conda/en/latest/user-guide/tasks/manage-environments.html#activating-an-environment

The only way I can make it work (and this is on conda/macOS) is replacing the <ENV>/activate script in the environment with this one-liner (where <ENV> is the full absolute path to the environment):

export $PATH=<ENV>/bin:$PATH

Then the Jupyter stuff launches fine (just to verify).

This is weird. The latest nightly is working for me with conda 4.6. What conda version do you have installed?
