ImagesService getServingUrl fails often

[Wilson MacGyver]

Hi,

We have a java app that calls ImagesService to get a serving url

via getServingUrl API call

I notice we get ImagesServiceFailureException A LOT.

Has anyone come across this?

Thanks

In my experience its one of the less reliable App Engine services. I had to change my app to store the serving url in one of my models. I recommend you do the same.

Thanks, actually that's what I'm doing. the problem is getting the initial serving url is failing a lot. :(

Sometimes getServingUrl fails if you call it too soon after uploading the image. How much time elapses between image upload and the serving URL call?

If you're still having problems, you can place the serving URL call within a task and repeatedly redo the task until it succeeds, then save the url into the datastore.

I thought of that too. It's 24-48 hours later after the images have been uploaded into google cloud storage.

I have a try/catch to repeat try up to X attempts. I'm just surprised how often it fails

Are you still having this problem? I noticed today that *every* request that I make to get a serving URL is failing with an ImagesServiceFailureException.  I'm not sure how long this has been going on - a couple of days at most, probably just hours.  There was no change in my code; just the repeated failure.  Is anyone else experiencing this?

It still happens every so often. I just catch the exception and mark particular file for retry later. With enough retries spaced out, I eventually get perma url for all of them.

not the best solution, but the only one I found that worked for me

Thanks for the response!  I realized that most of my problems were due to some empty URLs that I was passing to getServingUrl().  It turns out that I am not seeing consistent failure of the API.

glad to see you found the problem. I think imageService can use some better error messages :)
