I used the “Error Trigger” and then an action to send me a message in case of an error.
I also configured this Workflow as an error workflow in the settings of another worklow.
Unfortunately I can not activate the error workflow.
I get an error message saying that “Only workflows which have trigger or webhook nodes can be activated.” (see image)
Thank you! I overlooked this small but very essential sentence.
" As opposed to other workflows with a trigger node, you won’t have to activate the workflow when using the Error Trigger node. Once a workflow fails, this node automagically gets details about the failed workflow and the error workflow gets triggered."
