Enable Javascript in Response Preview #5803

App Details:

Issue Report:

1. Sending a request to some pages, keep getting the error ‘Javascript is disabled on your browser. Please enable Javascript and refresh this page’. The page works on the browser but on Postman it comes up with that error. Initially thought it was the page so tried another and still keep getting the error. Tried on other machines but they keep getting the error also.

The screenshot above shows the error in Preview mode but this error shows in Pretty or Raw mode also.

I can see a similar issue was open prior but got no resolution. (Error on POST request: «JavaScript is required. This web browser does not support JavaScript. » #3344)

The text was updated successfully, but these errors were encountered:

Hi, does not resolve my issue .

@arunkal1 This is not supported at the moment and we are tracking this as a feature request at #2646

I am facing the same problem. I want to send an an autheticated call on LinkedIn. It was working perfectly fine till few days back. Now it says ‘You need to enable JavaScript to run this app.’

Can someone guide me what might be wrong?

@swissarmychainsaw they dont want to allow it because of security concerns

they should at least give an option to enable that feature, it’s very inconvenient to manual copy&paste to some html online editor like this:
https://www.w3schools.com/tryit/tryit.asp?filename=tryhtml_default

I have this problem too, looking for a solution. This issue should be re-opened.

@nikandlv thank you very much for your solution. however, i am unable to use it as i use Windows.
Is there any ETA by which you are planning to release your solution for Windows?
again, thank you!

Hi,
we use Postman a lot, especially the integrated feature to get an Oauth Token via the Auth Code Flow.
Now our IDS changed and the login form is submitted via javascript.
This — similar to the topics mentioned above — does not work anymore now. Not able to complete the auth code flow with postman.

The deprecated Postman Chromeapp seems to do still do the job, but comes with its own drawbacks.. and: is deprecated.

The patch from @nikandlv only works for linux/mac versions.
I understand security concerns, but couldn’t this be made toggleable (as above mentioned patch is doing) — with disabled just being the default?

Would appreciate the ability to be able to have javascript enabled in the Oauth Login pages rendered by Postman.

If I am just missing a setting, or if you know a workaround / patch for windows — please give me a hint.

postman: You need to enable JavaScript to run this app

I’ve got a new API from the backend team in a new project, when I call the api it returns «you need to enable java. «, whereas I had used Postman for another project before. is it related to api, server or something else?

Yeah this looks like your calling the page rather than the endpoint and so is returning your index.html by the looks of it. I’d look into making sure you have the current URL.

6 Answers 6

I spent some times pondering on this trepidation.. and then suddenly i realized what was going on..

1. the endpoint does not exist, it could be a misspelling
2. not in the same directory as you expect it to be, try adding or removing «/» at the beginning of the url, particularly if you don’t specify the hostname, i.e. fetch(‘getusername’) is different from fetch(‘/getusername’) . . This acceptable in development but NOT when already deployed, it points to different path.
3. the endpoint may be working fine in the Development, but somewhere within in the Production/Staging, it generated some exception.

I don’t think that POSTMAN is capable of executing JavaScript in its console. Try doing the same in the web browser it will work (You won’t see this error message).

I updated Postman and now it works. I’m not sure if it was because of the update or the restart.

I had this problem with a project built using the new template in Visual Studio 2022 for a React app with .NET Core.

In my case I was only getting the response «You need to enable JavaScript to run this app» with calls to a new controller I added. Calls to the built-in WeatherForecastController were working just fine. My new controller was configured the same as the built-in controller so I could not figure out why this was happening. It has to do with how this project template creates both a React app and a back-end API both accessible on the same port. There’s a setupProxy.js file that defines routes that should be forwarded to the API. All other routes are redirected to index.html. This is actually what was happening in my case, because my new controller had not been added to setupProxy.js the middleware was redirecting the request to index.html, and because it came from Postman rather than a browser the message regarding enabling JavaScript is displayed.

The solution is that each controller must be explicitly mapped in setupProxy.js or else it won’t be proxied correctly. After making this change it worked perfectly in Postman as well as fetch calls from the React app.

const context = [ "/weatherforecast", // built-in controller than comes with the project template in VS2022 "/recaptcha" // controller I created (this line must be added) ];
