Slack alert has blank images

Hi. I configured a Slack alert to a dashboard, but it only send the images for the first 5 questions, there are 7 in total.

Curiously, these last images are hidden and to show them we need to click on "Show more". But i tried to send only the questions, not the dashboard, and they kept blank, even without needing to click on "Show more".

We use v0.49.11.

There's somebody facing the same?

what do you see in Metabsae when you click on the charts?

Hi Luiggi. I see the charts normally:

But when i send them on Slack throught alerts or alert subscriptions they don't load:


(The message says that "An error occurred while trying to view this card".)

Sometimes they just come blank on Slack, and don't show this error message.
