Alteryx zLib Error thrown on Server but not on Desktop

ccagle

Hello, 

We have a workflow that uses an outlook input tool to grab some email attachments and write them to a blob file. We then pick that file back up via the dynamic input tool and proceed to load the data to a SQL table ultimately. 

The problem is that this workflow will run on our desktop, but not on our Alteryx server - it throws the zLib error I've attached. I've already troubleshot this a bit - I can get it working on the server with a generic file, so this is telling me it isn't an access or path issue. It does say "To: email address must be specified" - this is specific to our case, but I'm wondering how this error can appear only on the server and not on the desktop. 

I'm attaching a copy of the error as well as a pic of the workflow with the tool where the error is thrown. Any help would be appreciated.

So I ended up finding and fixing the error. The issue is that we were passing a blob object to an excel file, and then pulling from that excel file (using the dynamic input tool) to put the data back into a sql table. 

The problem in this case is that the excel file we were using was corrupted, so the solution here was to create a new excel file, and point the data and retrieval there. 

So I'll accept this as a solution - I think the tricky part here is that the error that was throw was a 'zLib' error which seemed very hard to figure out what that actually meant.
