What is the best approach for managing errors within a shared observable in TypeScript?

I'm facing a unique issue and struggling to find someone who has encountered the same problem, which could imply that I am approaching it incorrectly.

The http request I am making looks like this:

return this.httpClient.post(`${this.route}/typegroups`, JSON.stringify(typeGroup)).pipe(share());

I have two subscribers to the returning observable and I want both of them to be notified in case of an error (or success). Currently, only the first subscriber receives the error notification.

First subscriber:

obs.subscribe((next:any) => {
  //Success Code
},
error => {
  this.notificationService.showError(error.message)
})

The second subscriber

obs.subscribe(next => {
    console.log("EVERYTHING WENT WELL")
  },
  error => {
    console.log("ERROR")
  },
  () => console.log("COMPLETED"));

The first subscriber is receiving the error notification and executing the error method, while the second subscriber is executing the next method, leading to a false impression that everything went smoothly. Any thoughts on why this is happening? Is there a better approach to handle this situation?

Thank you in advance for any assistance, as I am currently brainstorming to find a resolution to this dilemma.
