XML Error with CPE

1

Hi,

We have a router which successfully connects to GenieACS but on the periodic inform things fall apart and GenieACS closes the session (looked in Wireshark).

We can see the following in the GenieACS debug log which indicates a missing quote from the XML. Is this a CPE issue or can we workaround with GenieACS by ignoring it somehow rather than closing the session?

Any help would be appreciated.

I believe there is a config option to be more forgiving of bad XML. I don’t recall what that option is right now.

But working around bad XML at the GenieACS layer is the wrong way to go about this. You need to file defect with the vendor so they can fix the issue correctly.

Hi,

Fully agree but given that I know it will be a slow process for the vendor to fix, I was hoping to make GenieACS more forgiving :slight_smile:

If anyone knows the config for this I would be grateful.
