Requiring plugin via composer results in dependency errors

[TheFunkyMonk]

Description

I can install this plugin through the plugin store just fine, but when trying to install via composer as outlined in the readme, it results in the following error:

Using version ^1.2 for craftcms/aws-s3
./composer.json has been updated
Running composer update craftcms/aws-s3

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Steps to reproduce

1. From project directory, run composer require craftcms/aws-s3

Notes

• I also attempted to install using the composer binary included in Craft rather than my system one (running ./vendor/bin/composer require craftcms/aws-s3), which resulted in the same error.

Additional info

• Craft CMS version: 3.7.16
• Amazon S3 plugin version: 1.2.15
• PHP version: 7.4.21
• Database driver & version: MySQL 5.7.34
• Plugins & versions: N/A

Can you, please,

1. nuke the vendor folder
2. delete the composer.lock file
3. run composer update
4. Try requiring the plugin again?

Same issue with a clean install

Not a proper fix, but I had this issue in August and was able to make the install work by spec'ing an older version. If it's the project I think it is then I used v1.2.12.
