Memory profiler is being disabled while running Chrome dev-tool on Node inspector

I am trying to find away to analyze the memory consumption in a NodeJS application. I am trying to use Chrome dev-tool on top of node inspector. It's quite basic to start and I am listening on default 9229 port as suggested here.

After connecting to the port from chrome, I can see the consoles and files under Node but I am unable to run memory snapshots. It's just disabled.

Opened the inspect screen and clicked on the inspect.

Opened the inspect screen

Then I see these options completely disabled.

disabled 1 disabled 2

On hover of record button, I see a message "Another profiler is already active" which I don't have a clue to.

What could be the underlying issue here?

System specifications

Chrome - 83.0.4103.97

OS - Windows 10

Node - 8.9.4

Any help is appreciated!

Solution

  • Finally after trying out different versions, new Microsoft edge, I found out that it's an issue with version incompatibility.

    I tried with Node 9.11.1 and it didn't work. But at end switched to 12.16.1 and it works there. For now I assume chrome/chromium dev-tools supports higher versions of NodeJS.
