Variables must be the same as in DECLARE statement including the $ and same types.

In you case, the good name for the variable is $id and not id

"variables" : {"$id":10}

Both of these errors indicate that the specified file is not a valid zip archive. So I expect something is going wrong with the writing of the file (by the step prior to find-and-replace).

I would start by stopping the process after writing the file and seeing if the file is present on the filesystem and whether it can be opened manually using Word. This should bisect the problem and narrow it down to a writing problem or a reading problem.

It could be possible that an error is raised on the write and it's not being caught or whatever, leaving an empty or un-flushed (open) file. So having a way to monitor that step is probably a good idea. Writing to a log comes to mind as how you might manage that.

Inspecting the particular cases where there is a failure and managing to reproduce it are going to be critically important. If that's not possible, it's going to be a tough road of guesswork and disappointment on both sides.

looks like some authorization issue. Please cross check if the instance principle has all the required permission assigned. Please review this document [Publishing Custom Metrics][1] and [Overview of Monitoring][2]

After review/trouble shooting.

The OPCItem object provides methods to read the current value of the item in the server and write a new value to the item. I have included these facilities into this dialog. The read method provided on an OPCItem object performs a synchronous read from the server and can be configured to read either from cache or from the device. To read from cache both the group and item should be active, but synchronous read operations directly from the device do not depend on the active state of either the group or item.

Adding the following code allowed me to assign to variable.

I had a similar issue, I realized that it was working with the open JDK downloaded from https://jdk.java.net/archive/

I opened a ticket and Oracle is working to solve this. It was happening when installing Red Hat JDK.

According to RFC 1918, addresses in the 192.168.0.0-192.168.255.255 range are private. Such addresses can be used internally by any network so they're often used inside an organization. They cannot be used on the Internet since they aren't unique. Why my ip address starts with 192.?

I think that your local network is somehow preventing that connection. But without further details nobody can actually tell as far I know.

If you are running everything on the same computer you may want to take a look at "loopback" address. Usually 127.0.0.1 , that should loop back to your machine.

If you want to run a full server you may need to dig more into networking and want to understand how networks function.

This is not normal. It sounds like a bad implementation done by somebody who didn’t know any better.

Depending on the reference types they used to build this structure you could argue it is forbidden. DataType Nodes should only be the source of HasProperty, HasSubtype, and HasEncoding references.

edit: The path you mention is Root -> Types -> ObjectTypes -> BaseObjectType. Are you sure the Nodes you're finding under here are Variable Nodes with values or are you just seeing additional types defined by this server?

I can't help with the python part but here's an example of how to extract the hyperlink URLs themselves, rather than the text that the links are applied to, which is what think you're after.

Each slide in PPT has a Hyperlinks collection that contains all of the hyperlinks on the slide. Each hyperlink has an .Address and .SubAddress property. In the case of a URL like https://www.someplace.com#placeholder, the .Address would be https://www.someplace.com and the .SubAddress would be placeholder, for example.

It looks to me like you're trying to build the ExtensionObject that contains your filter structure using the NodeId of the Node you're creating a MonitoredItem for instead of the NodeId that identifies the DataTypeEncoding of the filter structure you're using.
