Configuration information for the importer has been lost (probably due to session timeout).

[Robert Pascual]

I tried assisting my colleague in uploading his CSV and now I'm getting the same time out error he received, "Configuration information for the importer has been lost (probably due to session timeout). Please restart the import wizard." when I click Validate before I proceed with upload. Restarting the import wizard doesn't work. I need help clearing whatever it is that is stuck in the back end so I can resume uploading bulk CSV.

I'm having the same issue now, anyone ever find a solution to this?

I'm getting this error as well after clearing the cache:  

"Configuration information for the importer has been lost (probably due to session timeout).  Please restart the import wizard."

What are the steps to clear the previous import data and start fresh?

Thanks,

Cecilia

Hi @Robert Pascual ,

Are you still experiencing this problem?

[Anne Macleod]

I'm having the same issue. My file is 689kb but just prior I tried uploading a file that was inadvertently too large (before I did this I had uploaded around 1800 tickets. Initially I got stuck 1% at the validation step so I cleared my cache and then this problem occurred.

Cheers,

Anne

Hi Robert,

Welcome to the Atlassian Community!

How large is the CSV file you are importing?

Also, what are you importing? Issues from another ticket system or project configuration?

I am having the same issue. Regardless I try different size files. I am importing some texts which explains some user stories and acceptance criterial. I managed to import good number of them, but got stuck with this error all of a sudden. Could someone help please?
