Create visualization with Lens Error

[kbujold_wr]

Hi, we are using elastic 7.9.3

After a fresh installation, if we navigate to the Visualize panel and select Create visualization / Lens we get can error saying "Unexpected token u in JSON at position 0" on the UI.

If we go to the Discovery panel and select the filebeat-* index and then try to create the visualization then we do not have an error and its successfully created.

Any idea how to resolve this issue?

Thank you,
Kris

Hi @kbujold_wr ,

is the error reported only in the console or does it prevent from showing the Lens editor?
Would it be possible to have a screenshot?

There is nothing on the console other than the error message. But I have noticed these difference in the query with a working setup and a non working one.

Not working
