Invalid argument warning

chcameron · March 30, 2017

I'm trying to use Alfred for Trello v1.5 by Miko Magni and yesterday I was using it just fine. However today I'm getting an error.

Warning: Invalid argument supplied for foreach() ...

The warning goes on to list a filepath but it's so long I can't see the actual end of the path, but my guess is it's pointing to the php file in the workflow folder. Here's that file's contents (see line 44 for the "foreach()"):

This morning I updated Mac OS with some small patch, and am currently on Sierra 10.12.4 ... my guess is something in this update broke something? Maybe? Any help here?

Hello and welcome, @chcameron,

When making a request or a bug report pertaining to a specific workflow, please do not open a new thread to discuss your issue.

Making a new thread, while it seems like it’ll give your problem visibility, will only fragment the discussion and make it less likely the author and users of the workflow (the people that can actually help) will see it. Instead, search for the official post of the workflow and ask your question there.

Also, please always start by reading the Reporting Problems with Workflows thread, and the others it links to.

Here’s the thread for the Workflow in question.
