I ran into the same issue when updating @apollo/client from 3.6.9 to 3.7.0. I reverted back to 3.6.9

Hi @groznikg, I use @damilgra 's workaround. In your package.json, instead of "@apollo/client": "^3.6.9", delete the circumflex^ to force npm to use the working version 3.6.9: "@apollo/client": "3.6.9", And wait until it is fixed 😃
