write_metadata() seems broken

In my recipe I do:




output = dataiku.Dataset(get_output_names_for_role(df_name)[0])
metadata = output.read_metadata()
metadata['custom']['kv'].update(meta)
output.write_metadata(metadata)


yet I get this in the logs:




[03:44:37] [INFO] [dku.utils] - output.write_metadata(metadata)
[03:44:37] [INFO] [dku.utils] - File "/home/dataiku/dataiku-dss-4.0.8/python/dataiku/core/dataset.py", line 872, in write_metadata

Something is wrong, I think... Anyone can enlighten me?

Hello,



We could not reproduce your issue on the latest version of DSS (4.1.2). We ran the following code:




output = dataiku.Dataset("mydataset")
meta = {"foo": "bar"}
metadata['custom']['kv'].update(meta)
output.write_metadata(metadata)


with the expected results. Note that we added the line `meta = {"foo": "bar"}`.



Could you upgrade to the latest version and try again?



Cheers,



Alex
