The "level" property of "pino.transports" did not work as expected

[pan93412]

Environment

{
  "dependencies": {
    "pino": "^7.0.1"
  }
}

$ node -v
v16.11.1

I'm in darwin/arm64.

Description

Consider this code:

const pino = require('pino');
const transport = pino.transport({
        level: "trace",
        target: 'pino/file',
});
const log = pino(transport);
log.error("Error!");
log.warn("Warn!");
log.info("Info!");
log.debug("Debug!");
log.trace("Trace!");

I expected it can print the log with the range from "error" to "trace"; however, it only prints the log with "error", "warn" and "info" level.

Expected Result

It would be worked like this code:

```js const pino = require('pino'); const log = pino({ level: "trace" }); log.error("Error!"); log.warn("Warn!"); log.info("Info!"); log.debug("Debug!"); log.trace("Trace!"); ```

{"level":50,"time":1634271718112,"pid":27365,"hostname":"pan93412-mbp.local","msg":"Error!"}
{"level":40,"time":1634271718113,"pid":27365,"hostname":"pan93412-mbp.local","msg":"Warn!"}
{"level":30,"time":1634271718113,"pid":27365,"hostname":"pan93412-mbp.local","msg":"Info!"}
{"level":20,"time":1634271718113,"pid":27365,"hostname":"pan93412-mbp.local","msg":"Debug!"}
{"level":10,"time":1634271718113,"pid":27365,"hostname":"pan93412-mbp.local","msg":"Trace!"}

Actual Result

{"level":50,"time":1634271603343,"pid":27301,"hostname":"pan93412-mbp.local","msg":"Error!"}
{"level":40,"time":1634271603343,"pid":27301,"hostname":"pan93412-mbp.local","msg":"Warn!"}
{"level":30,"time":1634271603343,"pid":27301,"hostname":"pan93412-mbp.local","msg":"Info!"}

pino default log level is info.

pino instance log level means the log allow to log. pino transport log level means the lowest level it can be received from instance.

If the instance log level is higher than transport log level, some of the log will be missing for transport.

This behavior is expected when using either transport or multistream. https://github.com/pinojs/pino/blob/master/docs/api.md#pinomultistreamoptions--stream

So should I do this instead?

const pino = require('pino');
const transport = pino.transport({
        level: "trace",
        target: 'pino/file',
});
const log = pino({ level: "trace"}, transport);
log.error("Error!");
log.warn("Warn!");
log.info("Info!");
log.debug("Debug!");
log.trace("Trace!");

It seems working when passing {level: "trace"} to pino()

Yes.
