Error in Studio workflow: 'Invoke Workflow: The given key was not present in the dictionary

[venkatesh_d]

I’m working on a complex workflow in UiPath Studio, and I keep encountering the error
‘Invoke Workflow: The given key was not present in the dictionary.’ I’ve double-checked my variables and arguments, but I can’t seem to pinpoint the issue. Has anyone else faced a similar problem or have suggestions on how to troubleshoot this specific error? Any help would be valuable. Thanks!

Hi @venkatesh_d ,

The error ‘Invoke Workflow: The given key was not present in the dictionary’ typically occurs when trying to access a dictionary key that doesn’t exist. Let’s troubleshoot this together:

1. Check the activity or sequence where the error is occurring. Verify that the dictionary you’re working with contains the key you’re trying to access.
2. Review the values of your variables and arguments to ensure they are being initialized correctly before reaching the problematic activity.
3. If possible, share the relevant portion of your workflow or code so that the we can take a closer look and provide more targeted assistance.

Feel free to update us on your progress or provide additional details. We’re here to assist you in resolving this issue.
