Ts-node-dev: Application fail to respawn after file modification has been detected

[bobbui]

Issue description

The application fails to respawn after a few restarts:
command :

cross-env NODE_ENV=development ts-node-dev --debug --files --respawn --project tsconfig.json --transpile-only --inspect --watch .env,../common/src, -- src/devIndex.ts

I think the most relevant part is Assertion failed: (napi_create_string_utf8(env, events->events[idx].path, NAPI_AUTO_LENGTH, &args[0]) == napi_ok), function fse_dispatch_event, file ../src/fsevents.c, line 147.

but a quick Google search returns absolutely nothing 😢

@bobbui I feel your pain. As temporary workaround I rolled back from 1.1.1 to 1.1.0, problem gone.

Revert to 1.1.0 does not work for me.

There were reports on this https://github.com/wclr/ts-node-dev/issues/241 not sure what it may be caused by. This also probably affects MacOs users. Try to use --poll option.

Assertion failed: (napi_create_string_utf8(env, events->events[idx].path, NAPI_AUTO_LENGTH, &args[0]) == napi_ok), function fse_dispatch_event, file ../src/fsevents.c, line 147.

I caught that error after upgrading my storybook (npx sb upgrade). It's weird, because there is no ts-node in my dependency tree.

[paulmax-os]

Same here within a nuxt(https://nuxtjs.org/) project. I had to upgrade a few dependencies, but nothing really crucial and since today it's randomly throwing those errors while being in watch mode for compilation. Upon some changes everything's compiling just fine, sometimes it pops up out of the blue. Haven't noticed any pattern.

Revert to 1.1.0 does not work for me.

Reverting also didn't work for me. After the error my CPU usage remains high (can see a 100% node instance in Activity Monitor)

[maxwellsmart84]

Same issue for me. I want to mention this that the port continues to stay open on my server and I have to look up the PID and kill it manually every time this happens (pretty awful DX)

I also see this which I haven't before, granted I am using this in conjuction with a graphql code generator named "nexus"

This works well. Thanks @wclr

[rista404]

Any progress on this one? --poll works but is quite CPU intensive

[taylorlapeyre]

This bug basically completely breaks this tool — is there anything we can do to help?

[paulmax-os]

On the nuxt side of things it seems that this issue was solved through this: https://github.com/fsevents/fsevents/pull/356

[alexanderMontague]

Having this problem still. --poll flag and reverting to 1.1.0 did not work. Using: ts-node-dev ver. 1.1.0 (ts-node ver. 9.1.1, typescript ver. 3.9.7) 😢

[lhermann]

I can confirm that. Even with --poll flag the problem persists. However, it does happen less frequently.

[wclr]

Try to upgrade.

[rista404]

Still having the same issue on v1.1.6.

[sliptype]

Can confirm, still an issue:

Same trouble here on 1.1.6. I was (as usual) suspecting the Docker file watches. But even when running this outside Docker (on macOS) the issue happens.

Any observations yet, if Is this issue introduced from node-dev or is it specific to ts-node-dev?

[lhermann]

If you still have this issue on macOS it is likely related to fsevents

Version 2.3.2 or newer should fix it, see here: https://github.com/fsevents/fsevents/pull/356

Fix:

npm update fsevents

(I can confirm it works on my environment)

[qqilihq]

I have been trying version 2.3.2 of fsevents this afternoon, but for me the original issue still occurs. (macOS 10.15.7)
