Since your setData hook/effect depends on the hey state, you need to specify the latter as a dependency in useEffect for the data loading.

Don't use Format-Table and Out-String -Width instead use a loop to construct an array of strings:

In the end this really isn't a plotly question. Somehow you need to pass new data to the plot.

You can generate this data using predict on your line model based on the provided date range:

First of all, you should be able to import Highcharts and its modules only once, even if you need to show two charts on a single page. So something like below will be enough:

The import is not correct. It should be:

https://cdnjs.cloudflare.com/ajax/libs/three.js/r128/three.module.js

three.module.js is the ESM build file whereas three.js is UMD. If you want to use ES6 import syntax in your app, you have to use the ESM version.

You have to think of a container as an individual minimal host. And in that case, when you say to your ticket_service app to call localhost it will call itself, which is not what we want.

Whenever using docker-compose, a docker network is created and the containers are configured to use it.
You can use that network to make your containers communicate with each other by their names.

In your case, as the Jaeger container is called jaeger, you have to configure the endpoint of your JaegerExporter as follows:

You may use this awk that loops through all the fields and matches a field using regular expression ^P[LR]:Z: and appends it into a variable to print it in the end.

It's important to note that the Webclient class uses the RETR command to download an FTP resource. For an HTTP resource, the GET method is used. That means if you provide a URL that doesn't contains the correct parameters to a downloadable file, you gonna end up with some exceptions that are not handled because Webclient was replaced with System.Net.Http.HttpClient, that I recommend you use instead.

Below you can see a exemple of how the Webclient works, on your case you are getting "useless error" because you are on a async method. I would suggest to use the normal method like below to debug and get the correct exception.

The question is:

Is this a bug or the right way?

It is the right way.

/proc/$$/fd/1 is a symlink to testfile, so >> /proc/$$/fd/1 is the same as >> testfile. It is a separate child process that writes to testfile. When this child process terminates, you see the stuff it has written in the file. It has no effect on your parent process.

STDOUT_FILENO is not special, it's just like any other file descriptor.

Why child processes affect your parent process file descriptor position? Because duplicated file descriptors refer to the same open file description. Read it twice - "file descriptor" != "file description". It is like a double-mapping. We say, file descriptors are not copied, they are duplicated, they share the file offset and file status flags, because they share the file description. See man 2 dup and man 2 open.

When a separate process opens the same file, it has a separate file description, so it does not affect your process file description.

(It is so badly named. I mentally call "file descriptor" like "system handle" (because it can refer to anything kernel wants to) and call "file description" like "file data" (if it's a file, it can be anything kernel wants to). It's then clear - this "system handle" refers to this "file data" and "system handle" is duplicated between processes that means that two "system handles" refer to the same open "file data". And "file data" stores file position and file locks and such. Processes have "handles", not "data". "File data" are removed automatically, when the last "system handle" is getting removed (the confusing man 2 unlink).)
