Creating Vega visualization with Image in kibana v 7.13

My vega visualization is working perfectly on vega editor, but its failing on kibana.

On elastic stack version 7.9.2, the exception message is:

“External URLs are not enabled. Add vis_type_vega.enableExternalUrls: true to kibana.yml”

But no error / exception message with version 7.13.4, though visualization is NOT being created successfully.

No clue from debug logs (tried via Inspect)

Tried adding code block to vega but no luck:
config: { kibana: { renderer: svg } }
with reference Vega Image + Link display in Kibana - Elastic Stack / Kibana - Discuss the Elastic Stack

I'm expecting visualization to look like -- from vega editor

The code

Solved by updating kibana.yml

vis_type_vega.enableExternalUrls: true
