Namespace issue in latest version (0.11.0)

[randomletters]

Problem/Motivation

After updating AppDaemon to the latest version my custom namespace stopped working. It looks like it is not able to create the namespace during startup, so all my entities created under that namespace do not function as expected.

Expected behavior

During startup I create a custom namespace 'mynamespace' so I can take advantage of the persistent storage on custom entities. In the previous version (0.10.1) this functioned without error.

Actual behavior

Error shown below. Namespace not created and custom entities do not store data.

Steps to reproduce

Add a custom namespace to appdaemon.yaml

  namespaces:
    mynamespace:
      writeback: hybrid

Proposed changes

My current workaround is to downgrade appdaemon to 0.10.1 but I don't know how long that will work.
I looked at the diff for the two versions and it seems that the only obvious change was python versions, but there are some utility scripts that changed as well. Is there a test which confirms namespace functionality?

Here is the error I get in the AppDaemon Log:

Thank you. That helped.

The solution unfortunately involves deleting the stored data, but it allows the code to function.

Steps to fix:

Update appdaemon
Goto terminal
Goto appdaemon/namespaces
Remove mynamespace.db
Restart appdaemon

Closing this issue, as it seems it is a result of how AppDaemon is made and upgrades in Python versions. That is not something we can address from an add-on perspective.
