Hello guys,

I have a very simple power automate flow which gets triggered with a HTTP call.

When I visit the url in my browser, or when I perform a GET request on the URL in Insomnia, the requests is successful and I get a row in history indicating that there is a successful run of the flow.

However, when I make the same GET request on the same URL, using one of my apps, I am receiving a 400 error saying --

{\"code\":\"InvalidApiVersionParameter\",\"message\":\"The api-version '2016-06-01,2016-06-01' is not valid. The supported versions are '2015-02-01-preview,2015-08-01-preview,2016-06-01,2016-10-01,2017-07-01,2018-03-01-preview,2018-07-01-preview,2019-05-01,2019-06-01-preview,2022-09-01-preview,2023-06-01-preview'.\"}}",

There is no mention of this run in the history either.

After receiving the error, i made two changes before making the call. On the calling side(my app), I removed '443' from the URL and changed api-version to "2019-05-01", since it is provided in the error message. After making these two changes, I was still getting the error--

{\"code\":\"InvalidApiVersionParameter\",\"message\":\"The api-version '2019-05-01,2019-05-01' is not valid. The supported versions are '2015-02-01-preview,2015-08-01-preview,2016-06-01,2016-10-01,2017-07-01,2018-03-01-preview,2018-07-01-preview,2019-05-01,2019-06-01-preview,2022-09-01-preview,2023-06-01-preview'.\"}}","message":"Failed to send callback to [https://......

I then changed the api-version on calling side to 'boom', just to debug, and it failed with the following error--

InvalidApiVersionParameter\",\"message\":\"The api-version 'boom,boom' is not valid. The supported versions are '2015-02-01-preview,2015-08-01-preview,2016-06-01,2016-10-01,2017-07-01,2018-03-01-preview,2018-07-01-preview,2019-05-01,2019-06-01-preview,2022-09-01-preview,2023-06-01-preview'.\"}}","message":"Failed to send callback to [https://prod-](https://prod-.........

Location of access cant be a reason, as I have asked a couple of my pals to hit the URL from Germany and US in there browser, both runs were successful.

I have also tried omitting the api-version from the calls altogether, but then I receive the error indicating that the api-version is a requirement.

I am not sure why the same calls are failing when made via my app, whereas the ones made from browser and insomnia are successful.
