INVALID_TYPE: sObject type 'CaseComment' is not supported in describeCompactLayouts.

Hi All,
Did anyone faced such error as below:

INVALID_TYPE: sObject type 'CaseComment' is not supported in describeCompactLayouts.

I'm getting above error in Lightning, while clicking on Case comment on Case record.

P.S. Any help/direction is appreciated.

Thanks,
Sucharita

We had the exact same issue today, no idea why.  Case comments usually are just plain text, this one for some reason displays an icon that appears to be hyperlinked to open a page with the exact same error described above.
