K2 Five 5.2 Designer

 

We are currently in the midle of building a very complex workflow with several steps. After many successfull deployments, we are now getting this error which prevents deployment.

 

The error message, as always, is quite opaque. Any ideas on what the issue is?

 

What is systemName and why is it null? How can we correct?

Hi  @VA1 


 


Can you please try the following:


 



  1. Navigate to management site > Environment Library> Development

  2. Locate the "SmartObject Server," select it and click Edit 

  3. Ensure the "Set as Default" checkbox is checked


Also:



  1. Navigate to management site > Environment Library>Production

  2. Locate the "SmartObject Server," select it and click Edit 

  3. Ensure the "Set as Default" checkbox is checked

This is a Development server. Yes, the Development environment library is marked as Default and the SmartobjectServer Key/Value is accurate and set as Default.

Any other ideas?

HI VA1,


 


You can try the below, but before doing so, ensure that you have created a backup of your K2 DB.


 


1. You can try to Delete designtime version of workflow to revert back to the last major deployed version. This will restore the deleted references and allow the workflow to properly deploy with no error


 


2. Or you can check the mappings on your SMO, ensure that the values are all in sync


 


Should you feel that this post is of use and or an accurate solution to the raised question, I kindly encourage you to mark it as such
using the 'Mark as Solution', 'Kudo' andor ‘Me Too’ options.


 


Cheers,
Kate

Hello,

It seems your SmartObject is not referenced properly as per the error null value is being passed against the property which is not null.

 

Please try publishing your SMO again and map the properties accordinlgy. 

 

The reason for this could be you might have updated SMO but in the workflow it is still referring to the older one.

 

Hope above help.

 

Thanks

Hi,

I have the exact same error on a brand new workflow ( in k2 5.2 )

I checked the mapping of every called SMO of my workflow and i can't figure out where the problem is.

I even checked each called SMO method in object browser.

Is there a way to have a more precise explanation as which block is concerned?

 

Because as it is right now, it is very frustrating.

 

Regards

FYI I gave up on this, reverted back to the last successful deployment , lost a few days of work.

 

The K2 Five Designer is honestly a disaster, I hate it.

  1. Too much clicking around
  2. error messages are meaningless,
  3. references break all the time,
  4. no capability to do a global search and replace
  5. or even just a search (e.g. show me all steps that use the following SMO/property/method/data field/whatever),
  6. for complex workflows, multiple developers are unable to collaborate
  7. the list goes on.

Yes, I realize I can make suggestions on ideas.k2.com and I will do that.
