Dashboard not rendering funnel

[kpthatsme]

Bug description

This dashboard fails to render the step funnel in the top left, showing an error message.

Clicking into the funnel it works and loads properly.

Attempting to re-add to the dashboard occasionally works, but ends up making the other funnel (trend) chart not render.

I think this has to do with showing multiple types of funnels on a single dashboard i.e. trends vs. steps.

It looks like either the trends or the steps funnels will successfully render but not both.

Expected behavior

• I expect all valid funnels on the dashboard to render

How to reproduce

1. Visit the dashboard, 'Core Funnel' isn't rendered
2. Click into the funnel and it should render fine on the insights view

I think this might be something with showing a mixture of funnels with trends and steps? It seems like either one of those will load i.e. all the step funnels render properly or all the trend ones, but never both.

Environment

• PostHog Cloud

Additional context

I did see this in my JS console:

In order to be iterable, non-array objects must have a [Symbol.iterator]() method.
