S3, check if file exists => Error parsing XML: String could not be parsed as XML

[mumhftm]

Describe the bug

Calling Aws\S3\S3Client->doesObjectExistV2()

leads to the exception:
Error parsing response for HeadObject: AWS parsing error: Error parsing XML: String could not be parsed as XML at /aws/aws-sdk-php/src/S3/Parser/S3Parser.php:74

• Happens since V351.10.
• Last working version is 351.9.
• I tested almost all versions between 350.0 up to 356.11

Use no special chars (no whitespace or similar) in filenames of files on S3. Paths are simple, e.g. invoices/2025/506/2025-08-27_506-000030655_invoice.pdf

Regression Issue

• Select this option if this issue appears to be a regression.

Expected Behavior

It should just return a boolean, indicating whether or not the file exists on S3.

Current Behavior

It leads to the described exception.
Happens with all files.

Reproduction Steps

1. Place a file to an S3 bucket
2. Assign permissions to access the S3 bucket to an EC2 (with Ubuntu)
3. Install the AWS lib and PHP
4. Call the doesObjectExistV2()

Possible Solution

I would - obviously - review the changes:
3.351.9...3.351.10

Additional Information/Context

No response

SDK version used

351.10

Environment details (Version of PHP (php -v)? OS name and version, etc.)

PHP 8.3.6, Ubuntu 24.04.1, EC2, S3 Bucket, Access through assigned IAM role

Could it be related to #3173 ?

Hi @mumhftm,

Sorry to hear about the issues. Looking into this now.

[stobrien89]

@mumhftm,

I wasn't able to reproduce, but this does seem similar to the issue you linked. It seems like the server is sending back a body, or some utility is converting the HEAD response to a GET response. Would you be able to provide debug logs by adding 'debug' => true to your client configuration and providing the output for a failed call? Be sure to redact any sensitive information like account numbers.

It doesn't appear that you're using any 3rd party s3 implementations or libraries to access S3, but if you are, could you provide the names of the packages or services you're using?

Hi @stobrien89

Thanks.

The problem happens with Laravel 12, using league/flysystem-aws-s3-v3 V3.29 on top of aws-sdk-php.
Bug #3173 seems to be related to Laravel as well.

My investigations so far:

1. Creating an isolated example with a simple config doesn't lead to the exception.
2. So I added a log to see what config is passed to new S3Client(). It might be relevant for further investigations, but even the very same config didn't lead to the exception in the isolated example: "driver":"s3","key":null,"secret":null,"region":"eu-central-2","bucket":"company-portal","url":null,"endpoint":null,"use_path_style_endpoint":false,"throw":true,"report":true,"root":"stage","version":"latest"
3. Therefore, the difference might be something happening between instantiating S3Client and calling doesObjectExistV2($bucket, $pathToFile, false, []);
4. Double checked the reported problem: It also happens with most recent version 3.356.12, while it works with 3.351.9
5. All tests were done with calling doesObjectExistV2() where the file actually exists.
6. I hope you can see more with the debug output, which was done with 3.356.12

Here is the debug output (redacted sensitive informations, so things like filename-lengts might mismatch if that's relevant somewhere):

Hi @mumhftm,

Apologies for the delayed response. I'm not seeing a body explicitly sent in the response based on the logs, but the error message you're receiving indicates that's what is happening. Could you tell me which storage back-end is sending the response for these requests?
