Basic Authentication throws - No Transport providers available.

[rnarasim]

Hello:
I am testing this using the demo project provided. I switched to Anaplan Basic Auth instead of certificate authentication. I get the an error "No Transport Providers Available". Here is the complete stack trace.

Any thoughts?

Thanks for reporting. We're looking into this and will update as soon as we have the fix.

[shuvozula]

Just to confirm, the error trace was reported in Anypoint Studio when you tried to run the demo flow there?

[shuvozula]

Assuming you were using Anypoint Studio, did u provide values in the src/main/app/mule-app.properties file, like the Anaplan workspace ID and model ID?

[rnarasim]

Yes it was from Anypoint Studio. In the Demo - i just changed the Cert Based auth to Basic Auth. Entered the creds. For the Test Connection - not sure if WorkSpace and Module matters - i still entered those though.

[shuvozula]

We've been able to determine the issue and working on a patch. Will keep you posted as soon as it's available. Thanks for your patience.

[rnarasim]

Is this issue applicable only to basic auth?

No it seems to be affecting Certificate Auth as well. The patch will fix these issues.

[shuvozula]

Hi,
Thanks for your patience. We just published the bug-fix to the master branch in this repository and are working towards pushing these updates to Mulesoft's update site. Once its published there, you'll be able to update your connector to the latest version v1.1.2.
Thanks.

The fix has been pushed to master now marked as version 1.1.2.
