Unexpected keyword argument 'default'

Using both:

grafana-wtf explore datasources and grafana-wtf explore dashboards in our environment causes this to happen:

Traceback (most recent call last):
    File "/home/admin/.local/bin/grafana-wtf", line 8, in <module>
        sys.exit(run())
    File "/home/admin/.local/lib/python3.10/site-packages/grafana_wtf/commands.py", line 322, in run

        return cls(**payload)
TypeError: DatasourceItem.__init__() got an unexpected keyword argument 'default'

Grafana version 10.2.3

Our instance of Grafana has in the thousands of dashboards, so its unfortunately not feasible for me to find the specific one causing this issue, in order to post the JSON structure. This must have been a somewhat recent dashboard addition that caused this, as ~2 weeks ago this was working fine with no grafana-wtf version change.

As a quick fix on my end I was able to update the DatasourceItem class here:

grafana-wtf/grafana_wtf/model.py

Lines 161 to 170 in da92328

	class DatasourceItem:
	"""
	Represent a datasource reference within a panel, annotation, or templating (variable).
	"""
	uid: Optional[str] = None
	name: Optional[str] = None
	type: Optional[str] = None
	url: Optional[str] = None

with an extra argument:
default: Optional[str] = None

Hey @jwoodhouse your workaround above also works for my setting:

• grafana-wtf v0.20.0
• grafana (cloud): 11.4.0-79146

Would be happy to see this being patched 😄
