Company exemptions service not found

I’m trying to access the exemptions for a company (https://developer.companieshouse.gov.uk/api/docs/company/company_number/exemptions/exemptions.html).
Other requests, such as fetching the company profile work; however for the exemptions I am receiving the following error :

    "errors": [
        {
            "type": "ch:service",
            "error": "company-exemptions-not-found"
        }
    ]
}```

This is likely correct. Very few companies have PSC exemptions - or at least that I’ve encountered (try digging around banks / building societies for more). Try the following which do (as of 2020-02-24):
