downloadFile: weatherXML: nt_.gif Error

[gwichman]

anyone else seeing this? looks like it started showing up in my logs around 10AM this morning..

Is this happening during a conditions import or a forecast import?

Is this happening during a conditions import or a forecast import?

I'm not sure how to tell..?

It looks like it might be some transient problem since it only shows up in my logs 4 times yesterday and so far i haven't seen it since.

The error happens when it is dark out (nt for night) and no image was selected for the condition image.
During the day, if no image is selected by WU, the image name is not there. The XML file is sent with no image. At night nt_ is appended to the front of the image name. ex. nt_fair.gif. When the image name is missing WU send a value in the xml file the is nt_.gif. When wxml goes to download nt_.gif there is no such file on the WU site so you get the error.

If you can look at the Scheduled page and see what minute you are running the Conditions and the Forecast you can compare it to the error message determine which one ran. I have added several places in the code that checks for nt_.gif but as your error shows I haven't covered all of the import functions.

If you get a chance to check the run time vs the error time, if would give me an idea on which part of the code to add some more checking.
