Issue with Workflow Extensions webhookUrl

Hi,

I created an app, a workflow and a workflow extension.

The workflow should send data through the extension via a webhookUrl to our service.

I tested it with a webhookUrl from https://webhook.site, catching the posted data and then tested with reposting to our test environment via https://reqbin.com . This is working.

Now I changed the webhookUrl to our test environment, and it stopped working.

In the workflow history it always tells “success” but the post does never land there. It is no error shown. On the server is no request logged at all.

workflowExtension pointing to https://webhook.site/… => works

posting direct to test environment => works

workflowExtension pointing to test environment => does NOT work

test environment is here: https://bp-test.mailstore.com/webhooks/v1/hubspot

Any help is appreciated.

I created a new workflow and a new workflow extension (with the same settings).
Now it is sending the data to our endpoint.

It seems that changing workflow extensions back- and forth is not a good idea (like setting webhookurl from a to b and vice versa).
