Code is required, Please help me.
Thank you for your question.
I can confirm that it is not possible to restrict an issue from being transitioned until its linked issue is closed in Jira Cloud.
The reason for this is that that Atlassian only provide a rest API in Jira Cloud and do not provide a Java API in the cloud like they do in Jira Server.
The rest API in Jira cloud is restricted by Atlassian which means that the API's to provide validation and prevent workfow transitions do not exist in Jira Cloud meaning that you cannot define Conditions or Validators to restrict this behaviour in the cloud version like you could do in the server version.
You can see more detailed information on the differences between the cloud and server versions inside of our documentation page located here.
