Latest Update broke my widget.

almost the same here…

2023-01-23 00:08:25: Error on line 99:63: TypeError: undefined is not an object (evaluating 'piholeStats.dns_queries_all_types.replace')

Can someone please help me?

I also have not been able to fix it unfortunately.

It looks like the pihole stats values are not fetched anymore so that is why the error pops up.
It wants to convert the data to a string value but there is no data variable present at that point so it tries to convert null to string.

Does anyone know if the parameters have been changed for pi-hole?
I looked at the information of pi-hole but it still mentions the same parameters.

Hey there 👋

just updated the code. Because of changes of Pi-hole, you must use now the api token. You can create this one in the settings area.

Please update the parameters of your widget with the code inside:
{"url":"…","token":""}

Yes!! This works great. Just replaced the comma’s and dots again (in Europe that is the used decimal setting)

Yeah, perfect! Thanks a lot. One question: does the update feature work? It always shows me green, even though there is a new update… any idea?

Fixed!

@marked80
How did you replaced them?

Use a text editor for the script and put the second pic with your data into the parameter field if you long press the widget.

pic to is without blanks, the linebreak is only optical.

With a .replace function.
