Issue Opening Flow Designer: "Content Not Found" Error

[Ankit Balapure]

Hello,

I'm facing an issue in Flow Designer. When I try to open a particular flow, I get the following error message:

"Content not found"
"Your flow cannot be found. Flow sys_id:n"

The flow seems to be missing, but I am sure that the flow exists, and there have been no changes or deletions made recently. I’ve also tried clearing the cache, but the issue persists. Has anyone encountered this before? How can I resolve this issue and access the flow again?

Thank you in advance for your help!

Below is the KA extract for reference

Issue
When working in ServiceNow Flow Designer, you may get an error message stating "Your flow cannot be found. Flow sys_id:n." Trying to close the tab refreshes the page and prevents you from editing the flow. 

Cause
This error occurs because of invalid references to catalog item variables. This typically happens when these variables have been deleted from the system. 

Resolution

Follow these steps to resolve the issue:

1. Use the right mouse button on the popup window displaying the error.
2. In the browser's developer tools, locate the HTML code: <div class="ReactModalPortal"> and remove it.
3. The flow should now be editable.
4. Go to where the "get Catalog variables" action is used in your flow.
5. In the selected column, check for any invalid variable references.
6. Check other flow steps for references to deleted variables, noting that data pills may still display these as valid even when they're not.

Thanks @Bhuvan   , that was a key insight! I had several variables in the record producers set to active=false, but they were still referenced in the Get Catalog Variables action. Once I reactivated those variables (active=true) and removed them from the variable list in the action, the subflow got accessible again.
