Which tool versions are you using?

SDK: v14.2.0
Python: v3.11
Isolation mode: venv

Current Behavior

after updating the SDK from 13.7.0 to 14.2.0 te API seems to have changed the interface:

Traceback (most recent call last):
  File "viktor/api_v1.pyx", line 85, in viktor.api_v1._memoize.wrapped_fun

  File "viktor/api_v1.pyx", line 288, in viktor.api_v1.EntityRevision._from_json
KeyError: 'param_types'

Expected Behavior

I would expect some kind of changelog issue that the interface has been been changed

Workaround

For now I will revert back to viktor 13.8.0

Hi Wichard,

Thanks for notifying us, this is indeed a regression in the SDK. We will make a patch as soon as possible.

As workaround you could do the following such that you can continue to work with the latest SDK:

revisions = entity.revisions()
revisions[0]  # will resolve the EntityRevisionList internally
revision_number = len(revisions)

Hi Wichard,

We have just released SDK v14.2.1, which fixes this issue.
