Data Error - TypeError: Cannot read property 'length' of undefined

[oliveira0501]

I'm using Grafana 8.0.3 and I get the error when adding a map.

No configuration is started, when inserting the panel the error is displayed.
After configuration, the map is not displayed on the dashboard.

I'm using the latest plugin version 0.3.3

I have the same problem

I tried a lot of stuff to no avail. For example:

select now() as "time", 10 as FR works fine

select now() as "time", 100 as US works fine

but

select now() as "time", 100 as US, 10 as FR triggers the error

Data is formatted as timeseries

Any feedback will be greatly appreciated

So, @oliveira0501 and @SimonFuet you could resolve this issue?
I have the same problem with Grafana 8.0.5/ World Panel 0.3.3.

Nope, I'm still hoping for some help

I see the same thing on grafana 7.5.11/0.3.3 using postgres as a table datasource returning 3 colums metric,latitude,longitude with no null values.

I was able to fix it by not just having a valid query, but also tweaking the panel options to match how the query was working. Definitely non-intuitive, but it does work.

What exactly did you do? I am having the same issues on the most recent version of Grafana

Consegui corrigi-lo não apenas tendo uma consulta válida, mas também ajustando as opções do painel para corresponder ao modo como a consulta estava funcionando. Definitivamente não intuitivo, mas funciona.

Good Morning!

How did you manage to solve it?

[oliveira0501]

Can you share the solution details for me to replicate here?

I guess that this one is still unresolved ?
