'Font error in Firefox

I'm getting this error in Firefox 51.0.1 conole:

downloadable font: maxp: bad max_zones: 0 (font-family: "t" style:normal weight:normal stretch:normal src index:0) source: data:application/font-woff2;base64,d09GMgABAAAAAADcAAoAAAAAAggAAACWAAEAAAAAAAAAAAAAAAAAAAAAAAAAAAAABk4ALAoUNAE2AiQDCAsGAAQgBSAHIBtvAcieB3aD8wURQ+TZazbRE9HvF5vde4KCYGhiCgq/NKPF0i6UIsZynbP+Xi9Ng+XLbNlmNz/xIBBqq61FIQRJhC/+QA/08PJQJ3sK5TZFMlWzC/iK5GUN40psgqvxwBjBOg6JUSJ7ewyKE2AAaXZrfUB4v+hze37ugJ9d+DeYqiDwVgCawviwVFGnuttkLqIMGivmDg (unknown)

Chrome does not show this, and Safari shows several warnings that say Unexpected CSS token: : woff.css:1:# where # is a 4 digit number. There are no woff.css files in my project directory, only woff.json and woff2.json, so I don't know what to make of that.

Any ideas?

Here's an example (2022) of the error as asked above:

GET https://fonts.gstatic.com/s/chakrapetch/v8/cIflMapbsEk7TDLdtEz1BwkebIl1R5_F_gUk0w.woff2
[HTTP/2 200 OK 27ms]

The 200 response code suggests the file is served okay (as does an inspection of the response headers).

Error is:

downloadable font: maxp: Bad maxZones: 0 (font-family: "Chakra Petch" style:normal weight:500 stretch:100 src index:0) source: https://fonts.gstatic.com/s/chakrapetch/v8/cIflMapbsEk7TDLdtEz1BwkebIl1R5_F_gUk0w.woff2
