What version of Ajv are you using? Does the issue happen if you use the latest version?
6.12.5

Ajv options object

      meta: {
        $schema: 'http://json-schema.org/draft-07/schema#',
      },
      $data: true,
      allErrors: true,
      jsonPointers: true,
    }

Sample data

Your code

      meta: {
        $schema: 'http://json-schema.org/draft-07/schema#',
      },
      $data: true,
      allErrors: true,
      jsonPointers: true,
    };
    const ajv = new Ajv({

Are you going to resolve the issue?
throw error "serialize is not a function"
I set a debug point, it seems to be a string, not a function

You might be using a different version, can you check it?

Or maybe there is a problem with your build/bundling process.

Please provide a full isolated code sample that reproduces this problem
