问题
Currently I am trying to stash data into Cloudant DB from a notebook using Python's Pixiedust package. After establishing a connection it gives me this error when trying to insert data into the database.
nPy4JJavaError: An error occurred while calling o172.save.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 3 in stage 38.0 failed 10 times, most recent failure: '
Lost task 3.9 in stage 38.0 (TID 1811, yp-spark-dal09-env5-0046): spray.http.IllegalUriException: The path of an URI without authority must not begin with "//"
Please tell me how I can stash data into Cloudant DB from a notebook?

This issue has been addressed and a new version of PixieDust has been uploaded to PyPI. You can download the latest version in your notebook by issuing the following command:
!pip install --user --upgrade --no-deps pixiedust
Restart your kernel after the upgrade is complete.
You can verify your PixieDust version (this was fixed in version 0.40) by running the following command:
!pip show pixiedust
The output should look similar to the following:
---
Metadata-Version: 1.0
Name: pixiedust
Version: 0.40
