Undefined constant GuzzleHttp\Client::VERSION

[SteveMullen]

Describe the bug

PHP Fatal Error

This just started happening today. Nothing (that I know of) had changed. I did upgrade from aws.3.198.2 to aws.3.220.3 AFTER the problem began, hoping that would resolve it. But it did not.

Expected Behavior

Correctly get a list of files from an S3 service

Current Behavior

PHP Fatal Error

Reproduction Steps

All S3 operations seem to fail.

Possible Solution

Some forums suggest GuzzleHttp\Client::VERSION is no longer supported, but the call stack makes it look like the GuzzleHttp\Client::VERSION reference is in aws/phar/aws.3.220.3.phar/GuzzleHttp/functions.php

Additional Information/Context

guzzlehttp/guzzle 7.4.2

SDK version used

aws.3.220.3

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

PHP 8.0.18

I got this working by installing the AWS api via composer, and no longer using the straight php api. I would still recommend this be looked at - for folks using the php api and also have Guzzle installed via Composer.

Hi @SteveMullen, thank you for reaching out. I tried to reproduce the reported issue with the environment details that you provided and I was not able to, which indicates that the issue could be related with something else, maybe a conflict with different guzzle versions being load, or possibly there was a guzzle version locked down by the composer.lock file which would've required you to run "composer update"; You would've be able to check this by running "composer show guzzlehttp/guzzle" and this would've tell you the guzzle version that is being load, nonetheless I am glad you found a workaround.

For now I will close this issue!

Thank you!

I have come across the same error.
It occurred when I tried to use the PHP SDK to getBundles from Lightsail, when I ran this AWS php example: https://docs.aws.amazon.com/code-samples/latest/catalog/php-lightsail-GetBundles.php.html

I've followed it to the letter.

I was previously using the AWS composer bundles with no problems for S3 and Kinesis functions. It's only been problematic for the Lightsail which seems to build the client+credentials in a slightly different way. All the other clients (s3) have the credentials in the client creation, but Lightsail client doesn't allow this.

When I initially ran getBundles from Lightsail it threw an access error which I fixed by putting my credentials into an c:/user/.aws/credentials file, this fixed the credentials error, but then threw this Guzzle error.

cool - found the reasoning for this error in another discussion:

#2006 <--- here

Someone said this error was caused by multiple guzzle scripts running.. and sure enough, I had the AWS guzzle script AND the php guzzle loaded because I also required the main vendor autoload.

"require '../php/vendor/autoload.php'" <--- once I removed this the issue was resolved.

Cheers!

Started receiving this error recently - I'm not sure when it started though, probably in the last 6 weeks or so.
We did recently change from PHP 7.3 to 7.4.

The problem was present with v3.274.1, but I updated to 3.275.6 today to test and the problem is still happening.

Running aws-sdk-php v3.275.6
PHP 7.4.33
