Pattern function does not work un-quoted numbers

The pattern is expected to run against strings, it won't run if you specify a number.

What is the expected behavior for your rule? Do you just want to verify whether it's higher than X or is it really whether it just starts with 37?

In this example, we would want to assert that the example for this property starts with 37.

I see. In such a case you'll need to write your own function.

You could do something as follows

import { createRulesetFunction } from '@stoplight/spectral-core';
import { pattern } from '@stoplight/spectral-functions';

export default createRulesetFunction(
  {
    input: {
      anyOf: [
        {
          type: 'number',
        },
        pattern.schemas.input,
      ],
    },
    options: pattern.schemas.options,
  },
  function numericPattern(input, ...args) {
    return pattern(String(input), ...args);
  },
);
