PServer | PServer is a general purpose personalization server

You miss a closing parenthesis in this line of code:

Well it seems like the full path is not part of the event, hence you can not extract it from any field. Which fields get exported is part of the input filter implementation.

See the comments in the following link as an additional reference: Extracting fields from AWS S3 input paths in logstash

If the file path is static you could add it to the filename as a prefix.

Btw:

As you can see from

"file1" => "{"s3":{"key":"foo.2021-01-07.0.log"}}",

the field "key" is nested inside another field called "s3".

So if you want to extract the file name

You need to declare your variable interval as global variable to access it from everywhere in your file. A global variable can be declared outside of functions.

The value you receive is of type std::string and you want to use it as long. You can use toInt() to convert the variable from String to Long.

Try something like this:

I’m afraid it looks like browsers don’t support this, even though the spec says it’s valid.

Please see answers to your questions below:-

If I want to implement deep sleep functionality to the server, what would happen to the client? Does the client also have to reset at some point?

No the client does not have to reset, but you may have to reconnect to the server because in deep sleep the BLE connection is lost. If you want the connection to be established automatically as soon as the server wakes up, then you have to update the client code so that it continuously attempts to reconnect to the server. This way, as soon as the server wakes up, the client would connect to it and continue receiving notifications.

Also, is it advisable to use Characteristic.Notify in a deep sleep scenario?

In deep sleep the CPU will be off, therefore you will not be able to send notifications in this state. In this mode you will only be able to wake up the CPU through a timer or an external peripheral (e.g. touch pins). Please see the link below for more information:-

I hope this helps.

According to the documentation of desrializeJson(), the second input argument accepts char* with zero-copy; and, const char* or const std::string& with duplication.

Prototypes in the documentation (only the relevant ones):

its a logic error, you are having an if condition to check if no $threshold which is valid only for firs iteration. You could remove that check as it is not required.

It says in the spec (under gradientTransform):

This additional transformation matrix is post-multiplied to (i.e., inserted to the right of) any previously defined transformations, including the implicit transformation necessary to convert from object bounding box units to user space.

So depending on how you like to think about matrix multiplication, both answers are correct. In my way of thinking about it (transforms are applied right to left) #2 is correct. The gradient transform is applied first. Then the objectBoundingBox transform is applied. In pseudo code:

You have an issue with formatting the output of the first script when you output it as a variable that I have already mentioned. If you do thing the issue is with the Update statement, then I'd check your syntax is parsing correctly in PowerShell. It is also not clear how your function is receiving the $DB_Server and $Database values. I'm not absolutely sure this will fix your issue, but I think the code for your query function could probably be simplified, and here is a minimal example that works for me.
