[Bug]: stack gets printed regardless of format.errors

[fauxbytes]

The problem

Configuring format.errors doesn't seem to have any effect. The attached MWE instantiates 3 loggers with different configuration. All seem to result in the same behavior (which is: append error message to log message, and print the stack).

What version of Logform presents the issue?

2.7.0

What version of Node are you using?

v20.18.3

If this is a TypeScript issue, what version of TypeScript are you using?

5.6.3

If this worked in a previous version of Logform, which was it?

Minimum Working Example

import winston, { createLogger, format } from "winston";

const throwError = () => {throw new Error('** error message **')};
const foo = () => throwError();

const someFormat = format.json(); //or prettyPrint. or simple
const withErrors = format.combine(
  someFormat,
  format.errors({stack: true}),
);
const withErrorsNoStack = format.combine(
  someFormat,
  format.errors({stack: false}),
);

const transports = [new winston.transports.Console()];

try {
  foo();
} catch (e) {
  createLogger({format: withErrors, transports}).error('logger with errors(stack:true) :', e);
  createLogger({format: withErrorsNoStack, transports}).error('logger with errors(stack:false) :', e);
  createLogger({format: someFormat, transports}).error('logger w/o format.errors:', e);
}
