I faced same issue, it happens in Android, but works well in IOS. I guess this issue about Flipper Network.

For while, I commented

initializeFlipper(this, getReactNativeHost().getReactInstanceManager())

in this file /android/app/src/main/java/com/{your_project}/MainApplication.java

Whoever is still struggling with this issue. it's happening because of Flipper network plugin. I disabled it and things work just fine.

My workaround to make this work is commenting out line number 43

Try setting up the toggle-dark-mode event handler once when you start your Electron app.

Your code doesn't need to be in the ready event even.

Internally, the EvenEmitter hold an array of listeners for each event type. When you emit an event type, the EvenEmitter just goes through it's array of listeners and execute it. Therefore, the listeners are executed in the order it was added by addListener or on method.

To answer your questions there are two parts: a) it executes in the order you added the listener and b) it depends if the listeners are async or not. If your listeners are synchronous, then you can expect that behavior. If your listeners are async, you can't expect that. Even if your execute your async synchronously, they will not necessarily resolve at the same time because it's the nature of being async.

I have had the same issue. This is what I did:

1. I deleted the migrations folder as well as the dist folder
2. I ran npx mikro-orm migration:create --initial

After that, I restarted yarn watch and yarn dev and it worked for me.

Notice the --initial flag. I would recommend to check the official documentation. The migrations table is used to keep track of already executed migrations. When you only run npx mikro-orm migration:create, the table will not be created and therefore MikroORM is unable to check if the migration for the Post entity has already been performed (which includes creating the respective table on the database).

Ben does not use the --initial flag in his tutorial, he might have already ran it prior to the tutorial.

I fixed it by going to the actual file location of script.js and running the node command with that path. Like this:

node AppData/Roaming/npm/node_modules/@angular/cli/bin/postinstall/script.js

Actually that only helped a little bit. The problem was I was trying to install Angular using ConEmu GitBash and I should've been using cmd.

The answer you linked talks about the Cloud Functions lifecycle.

When you make a request to your function, the Cloud Functions gateway checks if any "Cloud Function Executors" are idle/stale/inactive. If none are idle, a new executor is cold-started and is sent the request. If one is idle, that executor is sent the request instead to save having to cold-start a new executor. When handling a request, you tell the gateway "I'm finished" by sending back a result (for a HTTPS Event Cloud Function, this is done by using res.end() or one of its variants; for most other Cloud Functions, this is done by resolving the returned Promise chain).

Once you've sent a result back, that "Cloud Function Executor" is marked as idle. When idle, any network requests are blocked and that executor may be shut down (terminated) at any time. As described above, an idle function may be marked active again if it handles another request which can lead to bizarre side effects if you haven't handled the lifecycle flow properly.

So to handle the flow properly, you need to follow these steps:

1. Validate the request (check for retries, syntax errors, missing authentication) and cancel it as necessary.
2. Do all of the work that you need to do.
3. Send back the appropriate result.

If the work that you need to do is expected to take a while, write a description of the job to your database (Firestore/RTDB) so it can be handled by a different Cloud Function triggered by the write to the database, and then send back the result as a description of where to look for updates on that job.

Looking at your code, eventEmitter seems to be defined as a global object that spits out "finished" events when it has finished doing the work in doSomethingComplex(). When myFunction is triggered the first time, all is well. But if myFunction gets reused, a second "finished" event will get fired. This works fine for the current request, but the request from earlier is still subscribed to eventEmitter and tries to send a second response resulting in the error you are seeing.

You have three options:

• Subscribe to only one "finished" event. (Solution Rating: Bad) (Think about if it fails and but a later request succeeds)
• Return a private version of eventEmitter from doSomethingComplex(). (Solution Rating: Okay)
• Convert doSomethingComplex() into a Promise-returning function. (Solution Rating: Best)

Based on the comments and the code, you've got a bit of a mess.

First off, your service should not have an @NgModule declaration: it's a service, not a module. Further, since your service isn't providedIn: "root", you need to actually provide it in your module.

Assuming AppModule is where this component and this service both live, you should have an app.module.ts something like this:

You have to add your custom commands like this. You can check out the discussion here - https://github.com/cypress-io/cypress/issues/1065#issuecomment-351769720 -

I followed the answer in this question and it worked for me, but I still don't fully understand why it didn't work on first addition then it worked on the next ones previously.
