Cannot run: ErrorId 1799

[dotKokott]

Hello!

First of all thank you for writing an open source alternative HttpClient.

I have a problem running it. When I try to do a GET to a local server I get a: 1799 -> DeviceNotReady error id.

Any idea what I am doing wrong?

Hi!

You error Id isn't an ADS error code, but a Win32 Code and means: ERROR_INVALID_SEPARATOR_FILE - "The specified separator file is invalid"

Did you already installed the Twincat (unofficial) function on your target system? You can check it under the path C:\TwinCAT\Functions\Unofficial\BeckhoffHttpClient\.

I'm wondering what can cause this error in your setup... 🤨 Are you able get the example on the README (https://dog.ceo/api/breeds/image/random) up and running?

Best regards,

FB

Yes the function is installed & I can see it under this path. I do have the rest of TwinCAT installed under E:\TwinCAT (not sure if that would make a difference)

The example from the README shows the same error.

🤔 I suppose it could be the problem, but I cannot reproduce it... I would advise you to try a couple things:

• Debug the httpClient FB ( in particular its private fields: startProcess, getLocalAmsNetId, initialized and startProcess.COMNDLINE)
• import the source code fot HttpClient in your project (in this case you may also move the twincat function folder to E: and change the hardcoded paths startProcess.PATHSTR and startProcess.DIRNAME)

Hi! Did you get all up and running? If yes, would your share your solution in this issue?

Hey! I had to move on for now and use the original Beckhoff httpClient. I hope I'll get around to it towards the end of this project. Should I get this running I will share my solution!
