XMLSyntaxError when format is JSON in CSW request

jankovicgd commented 6 years ago

I am trying to get a record in JSON but getting a XMLSyntaxError. The default format works. Sending a simple GET with outputFormat=application/json also works.

Input

csw = CatalogueServiceWeb(url)
csw.getrecordbyid(id=[id], 
                  outputschema='http://www.isotc211.org/2005/gmd', 
                  format='application/json')

Output

Traceback (most recent call last):
  File "/home/nikola/.local/lib/python3.6/site-packages/IPython/core/interactiveshell.py", line 2963, in run_code

XMLSyntaxError: Start tag expected, '<' not found, line 1, column 1

Additional info

Running on Ubuntu 18.04 in a jupyter notebook with python 3.6.5.

Thanks in advance.

Is there a CSW we can test against?
