[gunjam]

What version of OpenTelemetry are you using?

"@opentelemetry/auto-instrumentations-node": "0.44.0"
"@opentelemetry/resources": "1.24.0"
"@opentelemetry/sdk-node": "0.51.0"
"@opentelemetry/semantic-conventions": "1.24.0"

What version of Node are you using?

20.12.0

What did you do?

Updated from pino 8.21.0 to 9.0.0

What did you expect to see?

otel properties in pino log output

What did you see instead?

no otel properties in pino log output

Additional context

I've been switching between the two versions and it logs correct in 8 but not 9, so it's only the version of pino that seems to be causing this.

Logging out the pino instance you can see that the otel mixin has not been added to log trace ids, etc:

pino 8.21.0

[Symbol(pino.mixin)]: [Function: otelMixin],

pino 9.0.0

[Symbol(pino.mixin)]: undefined,

Not a bug.

Supported versions in doc state <9 see here.

Depending on the changes done on pino side it's maybe just needed to adapt range here.

I thought that might be the case then forget to check 🤦. Thanks for the clarification

The only change in pino 9 is the project dropping support for node < 18.

Opened #2163 to add support for new pino version
