Hi,
We have code in production that writes images to google cloud storage and
gets a blob_key for each file that it writes, then calls
images.get_serving_url_async() for each of the blob_keys
*This code has been working in production for years*, but today I started
seeing many TransformationError being raised for files that are images.
It's worth noting that it only seems to be a problem when I'm writing 25+
images to cloud storage.
Code is like this:
#data and filename specified earlier
with gcs.open(filename, 'w') as f:
f.write(data)
blobstore_filename = u"/gs" + filename
blob_key= blobstore.BlobKey(blobstore.create_gs_key(blobstore_filename))
image_url_futures.append(images.get_serving_url_async(blob_key,
secure_url=True))
#this is outside of function which created the image_url_futures
image_blob_serving_urls = [future_url.get_result() for future_url in
image_url_futures]
I looked at this question:
https://stackoverflow.com/questions/47703942/transformationerror-reasons-get-serving-url-images-api
- I can rule out that file isn't an image.
- I had assumed that "with gcs.open(...) would be synchronous, so I
assume the file has been written.
If I'm missing something or if you're experiencing the same issue, please
let me know.
Thanks
Rob
