My first guess is that we're requesting from the ORES v1 endpoint, and trying to parse it as a v3 response. @Ladsgroup may have already patched this?
My guess must have been wrong. Your patches for T178962 are deployed, and we should no longer be hitting the v1 API from the extension. Now I'm thinking these might be error responses?
Here are the MW loglines when this happens:
