How to get rid of the "Could not find any member to link for" errors or disable it altogether from Heroku build CLI?

Question

I'm on Scala 2.12.8 and I use the doc type links [[]] everywhere like so e.g.

import scala.concurrent.ExecutionContext

/**  
 * Some class documentation.
 *
 * @param ec the [[ExecutionContext]] instance to default to. 
 */ 

work fine in the IntelliJ IDE but it prevents me from deploying to Heroku when I run the command sbt stage deployHeroku because of million errors Could not find any member to link for while all the referenced types are well and available ... I get the same million errors when running sbt doc

How do you get rid of these doc errors or otherwise, how do you skip doing the doc step in the Heroku CLI deployment while running sbt stage deployHeroku?
