Requests for JSON return HTML when there is an error

[dbrnz]

A request for JSON content (using an accept header of application/vnd.physiome.pmr2.json.1) returns text/html when there is an error. This content includes the error log number. Could a suitable JSON response be returned instead? This would simplify debugging of client interfaces.

Unfortunately, these error log numbers are generated by the underlying Zope/Plone system and to override them is rather difficult. Please have your client check the HTTP status code before attempting to parse the content.
