Hi, I tried to use tutorial to "open and plot a shot" with debugging on.
"import matplotlib.pyplot as plt
dataset = catalog.level1.sources(url="s3://mast/level1/shots/30420.zarr/amc").to_dask()
plt.plot(dataset['time'], dataset['plasma_current'])"

and I get the following error. Would you kindly help me with a solution?

Based on other issues, I reinstalled intake==0.7.0, intake-xarray==0.7.0 and zarr==2.12.0.
Now I have the following error:

ValueError: No plugins loaded for this entry: intake_xarray.xzarr.ZarrSource
A listing of installable plugins can be found at https://intake.readthedocs.io/en/latest/plugin-directory.html

But compatible version of zarr is reinstalled. Any solutions?
