Azure-docs: Web Activity Fails with 2108 error, same web request works well from Postman

[brijrajsingh]

I have a web activity which calls an Azure function that expects a JSON payload and returns a JSON payload. My function is available on public endpoint and works well with header content-type-application/json and the json data in Body. While calling webactivity I get a 2108 error
{
"errorCode": "2108",
"message": "Error calling the endpoint. Response status code: ",
"failureType": "UserError",
"target": "WebActivity1"
}

There is no error defined here, I don't know what else can i do to debug this.

@brijrajsingh Thank you for reaching out. At this time we are reviewing the ask and will provide an update as appropriate

[KranthiPakala-MSFT]

@brijrajsingh Could you please check the response time of your endpoint?
The web activity will timeout at 1 minute with similar error if it does not receive a response from the endpoint.

[brijrajsingh]

My endpoint is responding well within few seconds only.

Hi @KranthiPakala-MSFT @brijrajsingh understand that this issue is from a while back, but just wanted to know if this was resolved ? I'm also encountering the same error. The web activity was working 100% previously and all of a sudden gave me this error code as well.

Please let me know, thanks!

@KranthiPakala-MSFT This still seem to be an issue as we are facing same issue. The api seem to be responding fine when invoked from Postman but fails when invoked from ADF Web Activity.
Api is simple - Uses basic authentication, tried configuring it web activity i.e. reading password from Azure key vault but always returns with 401 Unauthorized.

Just thought I would leave my two cents here in case anyone comes across the same problem.

In my particular case the API I was integrating was returning a HTTP status 301 redirect to include a trailing slash in the URL.
It would seem that the web activity in Azure Data Factory does not currently support following redirects, meanwhile Postman and other tools and libraries usually follow redirects by default or include a option for handling them.

The docs should probably be updated to mention this
