Salesforce Certified MuleSoft Developer II (Mule-Dev-301) Exam - Topic 4 Question 4 Discussion

A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?
C) Put the HTTP Request inside a try scope in Unit Successful. In the error handler, use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED.
A) Configure retrying until a MULERETRY_EXHAUSTED error is raised or the API responds back with a successful response.
B) In Until Successful configuration, set the retry count to 1 for error type HTTP: UNAUTHORIZED.
D) Put the HTTP Request inside a try scope in Unit Successful. In the error handler, use On Error Propagate to catch permanent errors like HTTP UNAUTHORIZED.

A Mule implementation uses a HTTP Request within an Unit Successful scope to connect to an API.

How should a permanent error response like HTTP:UNAUTHORIZED be handle inside Until Successful to reduce latency?

Show Suggested Answer Hide Answer
Suggested Answer: C

To handle a permanent error response like HTTP:UNAUTHORIZED inside Until Successful, the developer should put the HTTP Request inside a try scope in Unit Successful, and use On Error Continue to catch permanent errors like HTTP UNAUTHORIZED in the error handler. This way, the developer can avoid retrying requests that will always fail due to a permanent error, and reduce latency. On Error Continue allows the flow to continue processing after handling the error.

I’m a bit confused about the difference between On Error Continue and On Error Propagate. I think I might have seen something like this in the study materials, but I can't recall which option is best.

I practiced a similar question, and I feel like using On Error Continue would be better than propagating the error. So, I lean towards option C as well.

I'm not entirely sure, but I think putting the HTTP Request in a try scope could be a good idea. Maybe option C is the right approach since it allows for error handling?

I remember we discussed how HTTP:UNAUTHORIZED is a permanent error, so retrying might not help. I think option B makes sense to avoid unnecessary retries.

I'm feeling pretty confident about this one. Option B seems like the simplest solution - just setting the retry count to 1 for the HTTP:UNAUTHORIZED error. That should prevent unnecessary retries and keep the latency low.

Okay, I think I've got a strategy for this. Option C looks like the way to go - putting the HTTP request in a try scope and using On Error Continue to catch the permanent errors. That should help reduce the latency compared to retrying indefinitely.

Ah, I see what they're getting at. By using a custom container, we can avoid the 5-minute package installation step in each pipeline run. This should definitely meet the goal of reducing the overall execution time. Seems like a solid solution.
