i wanted to export a bpmn model that contains every event, action, and condition for https://www.drupal.org/project/eca/issues/3305587#comment-14666991 . but i ran into the following error on export:

the export of smaller models worked without any error. might be the case that not all fields are filled. the main purpose of that model was to see the micro copy of the model elements in context.

the export seems to work now. but when i've reloaded the model listing page before the export i got the following new error:

and when i tried to reimport the exported model i ran into the following (is that related and needs a follow up or is it ok in the scope of this issue - just wanted to mention it that it happened when validating the changes):

after the second error when going back to the models list page and reload the first error from #5 hasn't shown up again. but when i went to the model import page the same first error from #5 showed up now.

The first one from #5 is just a warning and a follow-up on the original exception caused by my lazy approach of solving the problem.

The other one, when importing the model, is unrelated. I suggest we keep this issue to the export problem. Once that's completely solved, let's have a look at the import in a separate issue.

I have updated the MR, so the warning should no longer appear - and the exception should also be resolved. If the warning appears once more, that may well be from the previous page request. You may want to refresh the page once or twice before then trying the export again with the latest MR.
