After creating a Workflow, cannot create states, due to following error :
Symfony\Component\Routing\Exception\InvalidParameterException: Parameter "workflow_state" for route "entity.workflow_state.devel_load" must match "[^/]++" ("" given) to generate a corresponding URL. in Drupal\Core\Routing\UrlGenerator->doGenerate() (line 209 of C:\damp\xampp\htdocs\drupal-10\core\lib\Drupal\Core\Routing\UrlGenerator.php).
- admin/config/workflow/workflow , create New Workflow MY_TYPE
- admin/config/workflow/workflow/MY_TYPE/states , press [Add State]. A generic error message pops up.
- admin/reports/dblog shows details in latest log message.
This happened after a change in Workflow Module, update of Devel module or Update of Drupal, since this used to work flawlessly.
The error happens upon buildOperations() of the newly created WorkflowState.
- having a newly created entity with id() is '' (empty string), gives the error "Parameter "workflow_state" for route "entity.workflow_state.devel_load" must match "[^/]++" ("" given)"
- changing the id() to NULL for the new entity gives the error "The entity cannot have a URI as it does not have an ID".
Solution is to avoid buildOperations on the new WorkflowState, to not bother core or devel module with this problem.
