I would recommend checking all your JS code parts first, normally this errors throw because there is something missing in content blocks, personalization blocks, delivery names.

 

If it seems correct to you, and as your are saying it happens inconsistently I would recommend opening a ticket to Adobe Support. I recently experienced a similar case on a project where deliveries where randomly failing, and in the end, it turned out to be an Adobe Campaign bug. So don't hesitate to write them if you are confident with your code. 

 

If you need something more, happy to help!

Hello @a_b_se ,

 

Just adding some additional information that might help, in addition to the previous reply.

 

If you’ve passed any extra additional data—such as target data, JavaScript variables, recipient data, or other personalisation parameters—user for personlizaiton data or show/hide conditions using if/else logic. If this data is missing at the time of delivery, it’s possible the delivery could fail. On the other hand, if the data is available, the delivery may succeed.

 

It would also be a good idea to analyze whether any personalization or dynamic content is failing due to missing data, as this could be the root cause of the issue.

 

Hope this helps.

 

Kind regards,

Parvesh

Hello @parvesh_parmar ,

I started the wkf again from failed mode and no errors occurred this time. This is really strange. A thing I noticed is that I have more recipients in the outbound transition of the delivery:

Hi @a_b_se , It will be better if you can share screenshot of error, but seems its javascript error. If you are passing addition data for personalisation in delivery and peronalisation is not configured correctly, check the alias value of addition data.

 

In might pass sometime if any dynamic block not using particular personalisation.
