ocean.py: ocean.py marketplace quickstart fails

In marketplace quickstart, the line asset = ocean.assets.create(metadata...) fails.

I copied the python code into a file play.py and ran that. Here’s the py file.

Here’s the traceback:

(venv) trentmc@trentmcLnv:~$ python play.py

During handling of the above exception, another exception occurred:

I was able to replicate your error, @surajsjain.

I fixed that error with this PR: https://github.com/oceanprotocol/ocean.py/pull/97

Notes:

originally the service had url aquarius.rinkeby.v3.dev-ocean.com (and similar for provider)
then we created the service aquarius.rinkeby.oceanprotocol.com, quite a while ago now. That’s the ones we’ve been maintaining. The READMEs etc were not updated at the time. The old services at dev-ocean were / are still running.
#93 was to update the READMEs etc. Done. Except the wrong new url was provided: it had the v3 in it, and it shouldn’t have.
The PR fixes that problem.
