Causes and resolution for "Error opening a workflow. Index was out of range. Must be non-negative and less than the size of the collection. "

May I know what causes this error message "Error opening a workflow. Index was out of range. Must be non-negative and less than the size of the collection. "

User made some modifications in a workflow and started seeing this error.

May I know what causes this behavior and what are the possible resolutions for this?

Thank you so much

Hi John,

This is not a common error and there may be something wrong that needs some technical investigation. If you're still not able to open the workflow I'd recommend that you open a support case with Nintex Support who will be able to assist in diagnosing this.


Thanks,


Callum

Because you subscribed to it? Or followed it? Or flagged it? Or tagged it? Why is the sky blue? Why is water wet?

As for John's original question / error - I have just run into the exact same issue. I was editing a workflow, saving periodically as I went along, and then my browser crashed. When trying to get back into the workflow to carry on, I now repeatedly get that same error message.

Unfortunately there doesn't seem to be versioning available for Nintex Workflow on 365, so unless tech support can work some magic, I've got a major problem

Hi Nigel,


Are you able to contact Nintex Support so we can get a case open to look at this, I'm quite confident that we'll be able to sort this out for you.

Thanks,


Callum

Hi Callum,

I logged a ticket yesterday. I've been sent through a word doc with 2 possible solutions, but neither works. The reference number is [ ref:_00D90q6Cb._500902Cupty:ref ]
