Workflow saves an empty "settings.json" file, and stops working.

[boris-chervenkov]

Every once in a while, the workflow saves the settings.json file as an empty file / 0 bytes. When this happens, the workflow does not work anymore.

Usually (but not every time), the error occurs when I enter some invalid input, like "cal <fweiuf" , then I add/remove characters from the query string. The error might also occur when I type the input a bit too fast.

When I run the main script via iPython:

In [1]: from main import Main

In [2]: main = Main("")

In [3]: main.execute()
16:18:58 workflow.py:2070 DEBUG    Workflow version : 1.2.1

.

And the UI shows:

When I edit the settings.json file to contain an empty JSON object, the workflow starts working again.

Hi @boris-chervenkov,

Have you tried the latest update? This issue should be fixed by v1.2.1. Please let me know if the problem persists.

Hi, @owenwater,

I thought I was using the latest version of the workflow, but apparently I was not. I'll let you know if something comes up.

Thank you again for the wonderful Alfred workflow :o)
