fixes #37

[robertsLando]

@jsumners @mcollina could you help me understand why tests are failing?

[robertsLando]

Even if I clone main repo and run tests the same two tests are failing.

creates pretty write stream with custom options for pino-pretty, via prettyPrint (default)

The problem is with pino-pretty@4.0.0, if I downgrade to version 3.6.1 tests are working

[robertsLando]

I think your tests are working because the cache is not correctly updated for dev dependencies and tests are running using an old prino pretty version. I suggest to fix the ci cache too @mcollina @jsumners. The bug so is not with this PR but it's with pino-pretty version 4+

[mcollina]

Turns out pinojs/pino-pretty#117 broke the tests here.

cc @jsumners I think pinojs/pino-pretty#117 has a bug, I'll open a PR there.

@robertsLando downgrading to 3.6.1 is definitely not the solution.

downgrading to 3.6.1 is definitely not the solution.

Was to show you where the bug is, I will wait for the next pino-pretty release 👍

[mcollina]

pino-pretty v4.0.2 was just released with the fix.

[robertsLando]

@mcollina Ready for review
