Gherkin error: defineParameterType is not defined

[losyukov-leonid]

What are you trying to achieve?

I use TS + Playwright + Gherkin. When I try to add defineParameterType I just getting errors.
If I use like in the documentation:

DefineParameterType({
  name: 'popup_type',
  regexp: /critical|non-critical/,
  transformer: (match) => {
    return match === 'critical' ? '[class$="error"]' 
    : '[class$="warning"]';
  },
};);

Given('I see {popup_type} popup', (popup) => {
  I.seeElement(popup);
});

The error is :

⨯ Unable to compile TypeScript:
src/step_definitions/parameterTypes.ts:3:1 - error TS2552: Cannot find name 'DefineParameterType'. Did you mean 'defineParameterType'?

Because in node_modules/codeceptjs/typings/index.d.ts there is declaration:

declare function defineParameterType(options: CodeceptJS.IParameterTypeDefinition<any>): void

If I use like this:

defineParameterType({
  name: 'popup_type',
  regexp: /critical|non-critical/,
  transformer: (match) => {
    return match === 'critical' ? '[class$="error"]' 
    : '[class$="warning"]';
  },
};);

Given('I see {popup_type} popup', (popup) => {
  I.seeElement(popup);
});

The error is :

defineParameterType is not defined
ReferenceError: defineParameterType is not defined

And if I change in node_modules/codeceptjs/typings/index.d.ts from:

declare function defineParameterType(options: CodeceptJS.IParameterTypeDefinition<any>): void

to:

declare function DefineParameterType(options: CodeceptJS.IParameterTypeDefinition<any>): void

and use it like in the documentation everything is working properly.

What do you get instead?

Correctly working defineParameterType function.
