fix : client is undefined in startTracing() in service.ts

[NawazTalha]

In rocket.chat/_templates/service/new/service.ejs.t

the function startTracing() is called with a client variable, but client is not defined anywhere in the file. This causes a runtime error when the service starts.

Steps to reproduce

• find the file Rocket.chat/_templates/service/new/service.ejs.t

• find this line startTracing({ service: '<%= name %>', db: client });

• Notice that client is never declared in this file.

• Try running the service—it will fail due to the missing client variable.

Expected behavior:

The function should use db instead of client because db is already defined from getConnection().

Actual behavior:

Error: ReferenceError: client is not defined

The service fails at runtime because client is never declared.

Additional Context:
This is a small fix that requires replacing client with db in startTracing(). I’d be happy to submit a PR for this.
