Workflow is correct and works, but when it now automatically needs to be executed the message will not send:
{
"Response": false
}

Now I re-open the workflow, click on recapture webhook.
Go to history, click on Re-execute Workflow
Then go through every step, the message is send. Any idea what happens?

Stranger is, at 9.38 the message is send!
Can it be that the message is in a qeue, gives an error to pabbly but is send a few minutes later anyway?
Does a waiting period needs to be added?

If you can put a delay of 1 minute just before the WA API, that would be great. In general, messages are queued over WA API for sending, as a result of which a slight delay in delivery is seen.
