Heroku-postbuild error when deploying nodejs and angular to heroku

Asked 2022-Feb-03 at 06:34

I have a app that is currently deployed on heroku and working perfectly fine. I created a new heroku app and tried to run the same branch. I installed nodejs and all the configuration is the same but for some reason the build is failing at heroku-postbuild: "ng build --prod". It works fine on the previous instance I have on heroku but wont work on the new one. I don't know what i am missing as the information on the error is minimal. I am attaching my package.json as well as the error message I get. any help will be appreciated and let me know if you need me to upload anything else.

Check if HEROKU_API_KEY is correct and that heroku_app_name is unique. Also this line seems sketcy: Detected both "build" and "heroku-postbuild" scripts Running heroku-postbuild. Maybe refactor heroku-postbuild in build and run only build.

Web Bluetooth & Chrome Extension: User cancelled the requestDevice() chooser

As discussed in https://bugs.chromium.org/p/chromium/issues/detail?id=994185, Web Bluetooth is NOT supported in Chrome Extensions popup windows.

It is supported however in a Chrome Extension "tab/options" page as it acts as a regular tab.

I haven't tried to reproduce this yet but I believe the issue is that Web Bluetooth doesn't have code to handle creating a permission prompt as a child of an extension popup window. It works for the options page because it is a normal Chrome tab and would also work for a standalone app window.

My suggestion would be to open a Chrome Extension regular page that contains some code to interact with nearby Bluetooth devices.

Web Bluetooth: Want to filter on manufacturer data when using navigator.bluetooth.requestDevice

Asked 2021-May-17 at 08:08

I see that Google Chrome has not implemented filtering on manufacturer data. Issue 707635, does not seem to have any progress.

The Web Bluetooth specification has an (unstable) spec for filtering manufacturerData when using navigator.bluetooth.requestDevice (https://webbluetoothcg.github.io/web-bluetooth/#example-filter-by-manufacturer-service-data

Does anyone know if there is any progress on this or made this kind of filtering work?

...

ANSWER

Answered 2021-Apr-13 at 07:44

The Chrome team has NOT made progress on this yet as you've noted. In the mean time, would filtering by device name, device name prefix, or GATT services work out for you?

You can try it with https://googlechrome.github.io/samples/web-bluetooth/device-info.html.

device.watchAdvertisements() is not a function. Web Bluetooth(chrome)

Asked 2020-Nov-03 at 18:23

I am currently trying to implement a webpage that will watch for the advertisements for any connected bluetooth devices.

I am following this example from the google chrome samples. Which is working on their webpage.

However when I run my code (copied from the example, but just in case its posted below) I get the "device.watchAdvertisements is not a function".

I was hoping someone could point me in the right direction as my only guesses are that:

A) I need to wait for chrome 87 (I have 86.0.4240.183 with the recommended flags enabled)

B) I am missing a library or import

C) User error (the most likely)

How can I access the light sensor value when using bbc:microbit over bluetooth?

Asked 2020-Sep-12 at 21:07

I am playing around with bbc:microbit using bluetooth web api to access the microbit service data (button event, led, magnetometer, ...).

It looks like the light sensor information are not accessible from the javascript API. From the microbit documentation, light sensing are accessible from the led service, but it looks like the lib is missing them.

The micro:bit Bluetooth profile is defined at:

https://lancaster-university.github.io/microbit-docs/resources/bluetooth/bluetooth_profile.html

It does not expose the light sensor information by default over Bluetooth. My initial thought for a quick workaround is that you could send the value over the Bluetooth UART service. I used the editor at: https://makecode.microbit.org/#editor to create a hex file for the micro:bit that seemed to work:

QUESTION

Long characteristic on web bluetooth

Asked 2020-Jul-02 at 10:14

BLE allows transmitting from 2 up to 256 bytes as the payload in a single burst. But, the long characteristics on android/ios can be read in chunks.
What happens on web-bluetooth? Can web bluetooth read long characteristics?
Does it split in chunks when the characteristic has more than 512 bytes?

...

ANSWER

Answered 2020-Jul-02 at 10:14

I don't know where you have got the number 2 - 256 bytes from. The length per Read Request / Read Blob Request is determined by the current MTU (which may be up to 65535 bytes). A characteristic value can be up to 512 bytes long. You can hence never read a value longer than this since a characteristic value is not allowed to be longer than 512 bytes.

Web Bluetooth defines that when a value is read, it shall "Use any combination of the sub-procedures in the Characteristic Value Read procedure to retrieve the value of characteristic". So yes if multiple requests are required (depends on MTU) to read the value, it will do so.

QUESTION

Web Bluetooth: how to check if bluetooth is enabled with javascript?

Asked 2020-May-19 at 16:32

Is it possible to check if bluetooth is enabled with javascript and is there any event to detect its change?

There is getAvailability() method in Web Bluetooth API:

getAvailability() returns a promise that resolves with true if the user agent is running on a system that has a Bluetooth radio and false otherwise. The powered state of the Bluetooth radio does not influence the availability because applications can prompt users to turn on the radio using requestDevice(). The availabilitychanged event can be used to detect changes in the availability of the Bluetooth radio.

This API is useful for developers to know whether they should show UI for Web Bluetooth or not to the user.

Web Bluetooth / Availability Sample

But as described, powered state of the Bluetooth radio does not influence the availability, it does not react on bluetooth turning off from computer settings.

...

ANSWER

Answered 2020-May-19 at 16:32

Correct, getAvailability() only tells you if the system has a Bluetooth radio or not.

There isn't a specific API that will tell the site if the radio is turned on or off. If requestDevice() is called and the user has the radio off, they will be notified about it in the device chooser in Chrome. They have the option to cancel the prompt or have Bluetooth settings open up for them to enable it. Either way, requestDevice() will reject with an error until Bluetooth is enabled in settings by the user.
