404 Resource not found
What does this mean?:
This error comes from some older recipes using deprecated actions.
Try to refresh the action by deleting the current action, 'search for a contact' in this case and replace with the latest action. In most cases this is taken care of automatically, but for very old actions sometimes the automatic conversion is not possible and hence the recourse to this manual workaround. A side effect of this could be that the field mappings that were using fields from this search may get invalidated, you will have to remap these fields. The fields affected by this will be marked by a red outline.
