NPrinting Preview error

[lanlizgu]

Hi, I am receiving the following error when trying to preview a NPrinting object:

The preview request failed with message: Object zzz of Sense App zzzz failed to render. ERROR: Navigator navigator=qliksense;proxyurl=zzzzz; appid=zzzz; identity=zzzz is stuck and can't be used anymore to resolve requests ---> Corrupt data [11]:Corrupt data(Column names are invalid)

This doesn't happen with other objects, so I understand that it is because I am doing something incorrectly with the column names, but I would like to know exactly what.

Thank you,

Hi,

Try to regenerate the connection cache and check that all columns used in the template are still available in the source document. Maybe one ore more were deleted or changed the name.

If you are running a recent version you can use the Check Entities button in the ribbon bar to have some suggestions.

Best Regards,

Ruggero

Hi Ruggero,

I found out what the issue was. As I was developing this in another environment, when I migrated the App and reloaded it, I didn't figure out that I was not adding a column (as it was loaded in another layer). Once I migrated also the previous layer to this environment, the issue dissapeared, as the missing column is available now.
