System information

• Version of Next.js: 7.0.2

Additional context

I think the problem itself is because ajv just bump it's version to 6.6.0 which remove equal function.

Work around

For those who also get this error, you can add ajv as dependencies with exact version 6.5.5

"ajv": "6.5.5"

As stated in https://github.com/epoberezkin/ajv/issues/889.

Adding the following lines to package.json worked for yarn.

"resolutions": {
    "ajv": "6.5.5"
},

This is definitely a bug that needs to be resolved.
