While working with Canvas using the "[eCommerce] Revenue Tracking" template Workpad. The embedded timelion visualization are throwing errors and showing a exclamation point graphic.
When I click on the error graphic is displays the following:
Whoops! Expression failed
Expression failed with the message:
[timelion] > unable to verify the first certificate
"stack": "Error: unable to verify the first certificate

I understand Canvas is in beta but this seems like a timelion issue with TLS. I am using a specified CA for TLS via HTTP and Transport layers across all of the Elastic Stack. From researching this error it seems to be specific from Node.js. I have double checked that the certificate chain is present in the CA PEM file which is set in all of the configs across elastic stack:
xpack.security.http.ssl.certificate_authorities: E:/Elastic Stack\Elasticsearch\config\certs
xpack.security.transport.ssl.certificate_authorities: E:\Elastic Stack\Elasticsearch\config\certs
