Hi! I'm having an issue with the plotly.JSONDataset. Saving a figure is working well. But when loading the same figure I get this error:

'utf-8' codec can't decode byte 0xe8 in position 6570: invalid continuation byte

Saving and loading the figure manually via plotly.io.write_json and plotly.io.read_json is working though. I also tried to use plotly.io.from_json via fsspec and that was working as well without issues. I had a look at the source code for the plotly.JSONDataset and I found a hardcoded "utf-8" in line 153. I experimented changing this to "latin-1" and then loading the figures worked. Is there a reason why "utf-8" is hardcoded here? Could this be a parameter to be set in the catalog definition? I also tried to set different encoding options via the catalog parameters fs_args and load_args but nothing worked.

Hello Jan, thanks for sharing your solution! In my understanding, it should work even if not provide an

encoding

argument as by default it’s should be

utf-8

https://docs.kedro.org/en/stable/data/data_catalog.html#load-and-save-arguments https://filesystem-spec.readthedocs.io/en/latest/api.html#fsspec.open We might need to double-check what value is used by default in case if not provide

open_args_save.encoding

. Would you mind opening an issue?

Okay will create an issue for that. In the general kedro repo or the plugins one?

Plugins, thank you!
