Hi  @Ariwibawa;

What happens when you click show me? you should be able to see the core of the problem in details if you click that option.

for now start a brand new workflow,observ if the error persist and ensure that your workflow field texts/variables does not contain any of the specified characters.

please check out with this formal documentation on how to delete a workflow without leaving references(https://help.k2.com/onlinehelp/K2Five/UserGuide/5.3/default.htm#K2-Workflow-Designer/Delete/Delete.htm).

Hi Widson,

Thanks for the reply...

Clicking on Show Me didn't open up anything. I'd deleted my previous workflow before i posted here. But it show up again, so i tried to delete it using your link and use How to delete a workflow in the K2 workflow designer. But it still show up on my K2 designer with some different icon. I didn't create any workflow variable, and its new workflow.

Nothing changed at my 2nd workflow, it still showed that error.

Thanks.

Best Regards,

Ariwibawa

Good day Ariwibawa

I would like to suggest that you clear your browser cache. Also, try making a new workflow on Internet Explorer if you are not using Internet explorer. If my above suggestion does not work, would you be so kind as to give us information on your K2 version and FixPack installed?

Kind Regards

Jacques.

Hi  @Ariwibawa;

Did you have some running of the same workflow instance before/or was the workflow deployed before, which version of k2 five are you currently on?

I think the deleted workflow left some orphaned entries---I suggest you to Delete all historical (log) data for selected versions---please dive into this formal doc here(https://help.k2.com/onlinehelp/K2Five/UserGuide/current/default.htm#Tutorials/Build/HelloWorld-Workflow/07DeleteArtifacts.htm), clear browser catch, restart the k2 host server...then you should be good to go!

Kind regards;

Widson.

Hi Jacques,

I opened up my workflow using IE 11, it still show the error. I have also done clear browser data & cache in edge, it still the same still error.

I didn't run any installation, i access the designer from https://trial.onk2.com/designer.

I clear out k2 instance from https://trial.onk2.com/management, reopened workflow and the error has gone now.

Thanks.

Best Regards,
