Should maybe start type_ocmf with an if not data-block. Do we want it to return None or {}?

What loglevel do we want for this @sveinse? Since we have not seen this before, maybe it's enough to set it to warning?

https://github.com/custom-components/zaptec/actions/runs/18541493246/job/52849850821 reproduces the error message by including "SignedSession":null in the input to the complete_session-type-conversion. Still not sure why it is null, but in the description of the completed_session-object in https://docs.zaptec.com/reference/api_chargehistory_get, SignedSession is listed as string | null, so I guess this is expected behaviour?

@sveinse Any chance you can have a look at these two PRs and prep a 0.8.4-beta anytime soon? Would be nice to have 0.8.4 out before the next HACore-beta hits.
