[Question] pino is ignoring debug and trace levels

[adan-ea]

Hello there,
I've looked for a solution to my issue but couldn't figure it out. Sorry if I overlooked somewhere.
I'm trying to log with multiple transports in my code but I can't manage to get the debug and trace level to work:

const transport = pino.transport({
    targets: [
        {
            target: 'pino-pretty',
            level: 'trace'
        },
        {
            target: 'pino/file',
            options: {
                destination: logFilePath // this goes to src/logs/logs.log and it works
            },
            level: 'warn'
        },
        {
            target: './pino-discord-transport', // custom transport that also work but still without the debug/trace level
            level: 'warn'
        }
    ]
})

The logger in itself doesn't have anything fancy

export const logger = pino(
    {
        base: {},
        mixin(_, level) {
            return level >= pino.levels.values.warn ? { traceId: randomUUID() } : {} // I don't think that's the issue, otherwise info wouldn't work
        },
        timestamp: pino.stdTimeFunctions.isoTime
    },
    transport
)

In my index.ts I have this for testing

logger.trace('trace')
logger.debug('debug')
logger.info('info')
logger.warn('warn')
logger.error('error')

And I get this in pino pretty:

[13:45:52.145] INFO: info
[13:45:52.145] WARN: warn
    traceId: "6a7667bd-8811-4ced-baab-f2975b2e07af"
[13:45:52.146] ERROR: error
    traceId: "cdbc6362-57ac-4adb-9990-a544251e80a3"

and this in my file

{"level":40,"time":"2025-12-03T12:47:13.199Z","traceId":"695d6fe8-e2a5-4641-96de-3f452679f99b","msg":"warn"}
{"level":50,"time":"2025-12-03T12:47:13.199Z","traceId":"849d7299-715e-4875-b19a-e34e9dc66aa4","msg":"error"}

I hope someone can help me or direct me towards a solution,
Thank you!
