KrisGraySFDC commented 4 years ago

This happens when you try to start it against lwc-recipies as well?

muenzpraeger commented 4 years ago

Yup, happens with lwc-recipes as well.

muenzpraeger commented 4 years ago

Ok, so the issue happens with return this.loadModule(filename, realLoad, request, parent, isMain); within the LazyLoader for /Users/rwinkelmeyer/.local/share/sfdx/node_modules/jsdom/node_modules/request-promise-native/lib/rp.js

KrisGraySFDC commented 4 years ago

Thanks Rene, thats good we can work on upgrading that.

Wonder if everyones having this same issue?

muenzpraeger commented 4 years ago

@KrisGraySFDC I unblocked myself (for now), by upgrading the dependency myself. It’s not beautiful, but it works.

@KrisGraySFDC Has the dependencies already been updated? Looks like this is not reproducible

KrisGraySFDC commented 4 years ago

I thought this was a transitive dependency, and thus we'd have to trace it back. By upgrading to the latest lwc you should have upgraded it.

The fix for this was released as part of version 2.1.0. Thanks for logging this.

Sadly I still seem to be getting this on 2.1.1:

@pbattisson - I'm looking to fix this issue, but still trying to repro this locally. @muenzpraeger - Can you elaborate on "I unblocked myself (for now), by upgrading the dependency myself". Which dependency did you upgrade and the version?

muenzpraeger commented 4 years ago

That's looong time ago. If I recall correctly I upgraded jsdom.

mcrdjr commented 4 years ago

I've been getting this same error also recently. The only thing I can think of that I've done is to install Jest so I could test my components. I have no test failures on the components and they install and run fine in my org.

Using both commands work fine. sfdx force:lightning:lwc:test:run and npx jest --coverage

mcrdjr commented 4 years ago

Okay, after trying all kinds of things yesterday and today, I looked at that .local/share/sfdx folder I removed the sfdx folder and dev server still did not start, which is what I guessed would happen. I then installed the plugin again sfdx plugins:install @salesforce/lwc-dev-server and the local dev server is now working again. yippie-kay-yay!

luke-rallyhc commented 4 years ago

I just started recently facing this issue. No real changes on my end. I didn't use local development server during the weekend and I came back and now it won't start up. It has been 4 days of it now working.

I've tried updating sfdx plugins as well.

harshitsinghal commented 4 years ago

As of today, I am facing this issue as well. Below are the commands I run on VS Code:

Command 1: sfdx plugins:update Command 1 Output: warning "@salesforce/lwc-dev-server > @rollup/plugin-alias@3.1.1" has unmet peer dependency "rollup@^1.20.0||^2.0.0". warning "@salesforce/lwc-dev-server > request-promise-native@1.0.9" has unmet peer dependency "request@^2.34". warning "@salesforce/lwc-dev-server > request-promise-native > request-promise-core@1.1.4" has unmet peer dependency "request@^2.34". sfdx-cli: Updating plugins... done

Command 2: sfdx force:lightning:lwc:start Command 2 Output:
Error: Unable to expose method "then"

I have just created a blank project in VS Code and authorised a new scratch org. Then I try and start the Local Dev server and see this error. Below is the snapshot from my VS Code: image

Meanwhile, I will manage with org based LWC development but would like to receive the fix once it is available.

Thanks!

Thanks!

It was working few weeks back, but again after update it is not working. image

Is there any timeline for this to get fixed. Any workaround ?

rajendrasnagar commented 3 years ago

Commenting, Just to keep this open. Still I am facing this issue & not able to get any workaround. image

xyc commented 3 years ago

@rajendrasnagar Could you try setting the env variable: SFDX_LAZY_LOAD_MODULES=false? For example: SFDX_LAZY_LOAD_MODULES=false sfdx force:lightning:lwc:start

rajendrasnagar commented 3 years ago

Hi @xyc , setting this variable doesn't work for me. However, FYI, I was previously using npm based cli. I uninstalled it and tried with standalone .exe. It didn't worked. Then, i uninstalled local dev plugins & re-installed it. Now, its working.

@xyc This did work for me.

geekyakshay commented 3 years ago

Uninstalling the local dev plugin and re-installing it worked for me too. Thanks to @rajendrasnagar

I had the same issue. Tried to fix with sfdx plugins:update and it did not work. Then I uninstalled the plugin and installed it again and now everything is working fine.
