Re: [EP-tech] EPrints CRUD module returning a 500 error

​HI,


Not directly related to this, but instead to SWORD. If you want to use the interface to update items (with different documents etc) and are using EPrints 3.3 if might be worth getting in touch with EPrints services as we (Kent) had some work done on the module. I think they have merged this into EPrints 3.4 but it was going to be released also on files.eprints.org at some point.


Regards

Liam

Hi,

 

I encountered the same problem when trying to add posts using SWORD.  If comment out the failing code in CRUD.pm to

 

                #return $self->send_response(

                        #HTTP_CREATED,

                        #$atom->param( "mimetype" ),

                        #$atom->output_dataobj( $items[0] ),

                #       'HTTP_CREATED',

                #        'application/atom+xml',

                #        'text',

                #);

I can both extract and add posts.  From what I understand this is some a debug code which seems to have been left by mistake (?).  Those better reading code are most welcome to comment on this – I may be VERY wrong!

 

However, removing/commenting out the rows above, adding an Eprints XML file (NewPosts.xml) to the archive is without problem:

 

christer@honeybee:~/test$ curl -X POST -i -u my_username:my_password --data-binary "@NewPosts.xml" -H 'Content-Type: application/vnd.eprints.data+xml' http://pub-dev21.slub.se/id/contents

HTTP/1.1 100 Continue

 

HTTP/1.1 200 OK

Date: Fri, 28 Oct 2016 13:00:12 GMT

Server: Apache/2.4.18 (Ubuntu)

Location: http://pub-dev21.slub.se/id/eprint/13823

Content-Length: 0

 

And yes, the post appears in the archive J

 

Regards,

Christer

Subject: [EP-tech] EPrints CRUD module returning a 500 error

 

Hi all,

 

I'm attempting to create a new EPrints record using the CRUD module. To test that I can access the repository, I'm using the example provided in the documentation. When I run the command from my terminal, I get the following response:

 

HTTP/1.1 500 Internal Server Error

Date: Thu, 23 Jun 2016 11:17:13 GMT

Server: Apache

Location: http://w01.eprintstest.da.ulcc.ac.uk/id/eprint/5252

Content-Length: 616

Connection: close

Content-Type: text/html; charset=iso-8859-1

 

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

<html><head>

<title>500 Internal Server Error</title>

</head><body>

<h1>Internal Server Error</h1>

<p>The server encountered an internal error or

misconfiguration and was unable to complete

your request.</p>

 

Weirdly, it returns a 500 Internal Server Error, yet it creates the EPrint record and puts it into the buffer. When I check the Apache logs, I see the following error message:

 

"Can't call method "param" on an undefined value at /perl_lib/EPrints/Apache/CRUD.pm line 1423"


When I review /perl_lib/EPrints/Apache/CRUD.pm line 1423, I see the following: 

 

return $self->send_response( HTTP_CREATED, $atom->param( "mimetype" ), $atom->output_dataobj( $items[0] ), );

 

Has anybody seen this error before? If so, could you point me in the direction of a possible solution?


Thanks! :)


Cheers,


Andrew
