In the link below, it is introduced that the VISA function corresponding to ibask in ni4882.dll is viGetAttribute, but is there a list of constants for viGetAttribute corresponding to each option of ibask somewhere?
I have found an article where is described how to solve this error, you shouldn't consider on LabVIEW parts, just follow troubleshooting steps to solve the issue.

Unfortunately the link you provided does not solve the problem. This is because we know in advance that the reason for the error is that the property corresponding to 0x23 does not exist in viGetAttribute. What I want to know is the viGetAttribute constant that corresponds to ibask's ibaSerialNumber(0x23). (If there is no way to know the serial number other than ibask, we welcome the provision of information to that effect.) Also, I'm not using LabVIEW.
I was wondering why you are avoiding using ibask as long as it is working?
About the error message, I doubt that there is something wrong with code in line 9, there should be call function in front of serial number (0x00000023).
The purpose was to complete with VISA without using ibask. Finally, I tried brute force (all Long type numbers) with viGetAttribute, but there was no constant equivalent to IbaSerialNumber.
If you are using USB seral port for VISA, here is "VI_ATTR_USB_SERIAL_NUM" command attribute for getting the serial number. You should put this in front of the seral number (0x00000023). Try to complete that in your side and see the results.
