Tell us about your environment:

• ndb version: 1.1.5
• Platform / OS version: macOs Catalina 10.15.2
• Node.js version: v10.13.0

Same here, as soon as I press "Stop" on the profiler to get the results:

I've reproduced this plenty of times. At this point it's a known issue of the project.

I have successfully managed to capture a profile with the latest NDB but it certainly doesn't work consistently.

@brendankenny notes that a possible workaround may be using console.profile() and console.profileEnd()

[shapkarin]

Does anyone solve that?

[segevofer]

same here, using mac with node v12.18.0 and ndb v1.1.5
please help resolve this issue...
