Re: [VuFind-Tech] Error message???

[Katharina W. <wol...@fh...>]

Hi Demian,

thanks for your answer. Is there a way to find out from where the
generateHMAC.php is called up in this case?

There are quite a few occurrences of item_id in the files I've worked with, but
afaik nothing I did in those files changed the way the parameter is handled.

How would I correct the error you described (set item_id)?
