unexpected image API failure

[John Smith]

Hey,

Today I have introduced a new feature in my application which includes the image.ServeURL() API call.

Unfortunately every call to this API returns an error:

"API error 1 (images: UNSPECIFIED_ERROR)"

This happens in my production environment but I fail to reproduce it on my development environment (also deployed to the app engine).

As far as I can tell everything is exactly the same in these two environments.

Relevant piece of code:

blobkey := fmt.Sprintf("/gs/%s/%s", bucketName, fqdn)

blobKey, err := blobstore.BlobKeyForFile(ctx, blobkey)

if err != nil {

return fmt.Errorf("blobkey failure: %v", err)

}

servingURL, err := image.ServingURL(ctx, blobKey, &image.ServingURLOptions{Secure: true})

if err != nil {

return fmt.Errorf("ServeURL failure: %v", err) // <-- fails here

}

May you please help me shed some light or suggest a path to debug this?

Thanks,

John.

I have created a new bucket and everything seems to work.

The old bucket does not work, but I still need to use it.

How can I fix this?

i would start by comparing my permissions on the 2 buckets.  perhaps there is a service account or something that needs permission on the bucket that is not working?
