PHP App Engine - Unable to Read Images in Cloud Storage

[Noel McKeown]

Hi users,

We are having some issue reading images stored on our bucket storage.

Using a php55 agg engine to serve the web docs.

Below is our environment and some sample code:

php.ini

extension = "fileinfo.so"

extension = "intl.so"

google_app_engine.allow_include_gs_buckets = "gs://safetyfreelancer-209721.appspot.com/"

app.yaml

service: phpmyadmin

runtime: php55

api_version: 1

handlers:

- url: /(.+\.(ico|jpg|png|gif))$

static_files: \1

upload: (.+\.(ico|jpg|png|gif))$

application_readable: true

- url: /(.+\.(htm|html|css|js))$

static_files: \1

upload: (.+\.(htm|html|css|js))$

application_readable: true

- url: /(.+\.php)$

script: \1

login: admin

- url: /.*

script: index.php

login: admin

Test Code:

<?php
use google\appengine\api\cloud_storage\CloudStorageTools;
try {

$photo = CloudStorageTools::getImageServingUrl('gs://safetyfreelancer-209721.appspot.com/uploads/profile_photos/4494316015c95582d11b344.51085825.jpg', ['size' => 100]);

} catch (Exception $e) {
	print_r( $e->getMessage() );
}
?>

<?php if( !empty($photo) ): ?>
	<img src="<?php echo $photo ?>" alt="<?php echo $photo ?>" /

<?php endif ?>

Test URL:

https://safetyfreelancer.com/test-permissions.php

Error on GCP Console:

PHP Fatal error:  Uncaught exception 'google\appengine\api\cloud_storage\CloudStorageException' with message 'Unspecified error with image.' in /base/alloc/tmpfs/dynamic_runtimes/php55_dynamic/fc2f1b4915ea2bca/sdk/google/appengine/api/cloud_storage/CloudStorageTools.php:810

The storage is public.

Appreciate if someone can assist pinpoint the issue.

Many Thanks,

Noel
