Gramps Web export issue [XML - can only concatenate str (not "NoneType") to str] & [GEDCOM - HandleError()]

Gramps 5.1.6
Gramps Web API 1.5.0
Gramps.js 23.12.0
locale: en
multi-tree: false
task queue: true


I’m attempting to export an XML from GrampsWeb but getting the following error:

can only concatenate str (not "NoneType") to str

Does anyone know how I can troubleshoot to see where this error is coming from?

I can create a separate ticket but I’m wondering if it’s the same root cause as I see a similar thing when trying to export GEDCOM format:

HandleError()

Just wanted to note I’ve updated Gramps to the following (new version of Gramps Web PI and Gramps.js) but am still experiencing this issue:

Gramps 5.1.6
Gramps Web API 1.5.1
Gramps.js 24.1.1
locale: en
multi-tree: false
task queue: true

Hi just wondering if there’s anything else I can/should add here to this post? Is anyone else experiencing this?
