FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

Describe the bug

After a recent install of npm and node, the autorest javascript and autorest java does not work. I tried to increase the memory by --max-memory-size=3888 but does not work.

npm 6.14.13 node v14.17.0 autorest 3.2.3

autorest packages

**Expected behavior**
It should run and parse the swagger.

**Additional context**
It throws a out of memory error.

Did you try using NODE_OPTIONS environment variable with a value of --max-old-space-size=4096

Did you try using NODE_OPTIONS environment variable with a value of --max-old-space-size=4096

Yes, I tried to set it in ide.

[timotheeguerin]

Feel like the IDE might just set the env variable for the npm script that trigger the autorest build and not the autorest process. Can you double check with setting as an environment variable. If it was set correctly autorest will log the node memory allowed

Hi, I upgrade Node to latest version v16 and delete npm and npm-cache folder in roaming, the autorest works now.
