Postman tool is hanging

moorthiraj · July 25, 2024, 7:10am

Hi All,

Anyone facing slowness in fetching the response around a minute in Postman tool or tool is hanging. I am using Postman for Mac & version is 11.5.0

If this issue is highlighted anywhere please loop in comments for my reference!

Thank you!

Hi @moorthiraj. Welcome to the Postman Community.

Can you confirm that this delay is not coming from the API server you’re working with? Also, what’s the size of the data being returned?

Hello @gbadebo-bello Thanks for the reply!

For a simple GET API which gives a response of 4 params with min values itself taking more time. It is not the loader I am saying. The response to format in JSON is taking more time in the latest Postman tool.

To highlight about hanging issue, I can’t able to use the tool when the response is gettting formattted

I’m not sure I understand you correctly. You get the response timely but the formatting takes significant time? Can you send a GET request to https://postman-echo.com/get?name=Moorthi and see if you experience the same?

Yes! You are corrrect!

When I hit 1 GET API, which probably fetches a bulk response took more time (which didn’t happened in previous version)

Then I verified few API’s for my testing (1 POST call and 5 to 6 GET calls) and following requests took more time to format and at that time the tool hung!

And I hit the request you shared and it behaved the same. Tool hung screenshot below,

Okay, got it! You’re using the latest version of Postman Mac. Can you confirm if you experience the same on Postman web?

moorthiraj · July 25, 2024, 1:54pm

Yes, version is 11.5.0

Postman web is working smoothly and currently I am using it. No issues with it !!

gbadebo-bello · July 25, 2024, 1:58pm

Okay, great! Please let me check in with the team to see what might be wrong here.

Hey! We’re sorry about the issue, we have identified a regression that causes certain responses to hang the Postman application.

We are working on a fix and will plan to get this out as soon as possible. We are tracking the bug here and will follow-up when it’s fixed.

### Is there an existing issue for this? - [X] I have searched the tracker for …existing similar issues and I know that duplicates will be closed ### Describe the Issue **_Warning that this example curl in postman takes a while to render and will freeze postman in version 11.2.34_** [request_that_returns_json_response_with_80k_double-quotes_renders_in_35seconds.txt](https://github.com/user-attachments/files/16090696/request_that_returns_json_response_with_80k_double-quotes_renders_in_35seconds.txt) [request_that_returns_json_response_with_160k_double-quotes_renders_in_70seconds_or_longer.txt](https://github.com/user-attachments/files/16090699/request_that_returns_json_response_with_160k_double-quotes_renders_in_70seconds_or_longer.txt) I've encountered a major parsing performance issue for specific json responses. In particular, it appears like postman is having an issue while rendering a large number of escaped double-quote characters (ie `\"`) contained in json-string fields. Could also possibly affect other characters or character sequence. Started about 2 months ago. Prior to this, postman would be able to render these with-minimal or without issues. I've attached 2x curl requests that easily invokes the performance issue using 80k and 160k double quotes returned in the response. I am utilizing the helpful httpbin api. I know the count sounds like a lot of characters, but prior to this issue, postman used to easily render these. There is no issue with the response time as the above example requests will respond in <1 second from the server. However when rendering, it takes **35seconds and 70seconds+ respectively** on my m1 macbook. I work with a web application that regularly spits out large json-encoded-text-blobs as a string field in its json response which will naturally contain many of these escaped double-quotes and I suspect that postman's ill rendering is to blame. Frequently, I have to force close postman and is obviously detrimental to my workflow. Also worth noting that collection runs are unaffected - it's just the rendering of the output when you manually execute a request. ### Steps To Reproduce Import my 2 curl requests into postman. Run the request and you potentially have to wait over a 30 seconds or a minute for it to render. ### Screenshots or Videos _No response_ ### Operating System macOS ### Postman Version 11.2.34 ### Postman Platform Postman App ### User Account Type Signed In User ### Additional Context? _No response_
