Issue on SOSS NIRISS nb

[wardhoward]

I installed (apparently successfully) and tried running the notebook 'soss-transit-spectroscopy' and successfully made it to line exposure = datamodels.SpecModel('calibrated_data_hatp1_transit.fits') where wavelength solutions are applied. It directed to a non-existing STScI website and failed:
http://stsci.edu/schemas/jwst_datamodel/spec.schema

Traceback below -- thanks for the help!

Hi @wardhoward, This is likely caused by a mismatch between the stcal package and other packages. I see in the requirements file that the pipeline is pinned to an old version. Can you try to upgrade the pipeline to the latest release? You can do so by running pip install jwst --upgrade in the same environment you created for this notebook. Let me know if this works!

This has not been touched in a long time. @wardhoward please open another ticket if you still see problems. Thank you!
