Concrete5 - Call to a member function getRelativePath() on a non-object -

(concrete5)

i have created custom block using block designer package.

i receive following error when copying block onto page. i don't receive error when adding it.

whoops \ exception \ errorexception (e_error) call member function getrelativepath() on non-object 

i have not altered code generated, , none of fields created set required.

it highlights line 63, is:

$urls = array('relative' => $pdfdownload_file->getrelativepath()); 

please click here screenshot of error message.

i can confirm have tried following:

• uninstalling block, deleting folder in blocks directory, , removing blocks table in database
• clearing cache
• re-making block after deletion

additional information

• concrete5 version: 5.7.5.8
• the server running php version 5.4.

any suggestions, or resources appreciated. thank you.

i assume implemented check whether or not file found (an object). seems file particular block got deleted , tried retrieve relative path non-existing file (should object, it's "null").

so build in check for version 2.4.2. shouldn't have problems anymore of version of block designer.

in case you've got other issues, can post support tickets on concrete5.org site product:

https://www.concrete5.org/marketplace/addons/block-designer/support

i notified email created ticket/thread. i'm not on every day/week, that's why missed in first place.
