Composer HTTP Authentication: unhashable type: 'dict'

[strarsis]

Just made a guide for this, including the correct configuration in Trellis:

[Guide] Using the `ACF PRO` official install method with Bedrock/Trellis

Bedrock For development, use an auth.json file in the Bedrock project folder – but it should not be committed to the repository, but rather added to .gitignore as it is a secret (the ACF PRO license), similar to the .env file. { "http-basic": { + "connect.advancedcustomfields.com": { + "username": "[ACF PRO license key]", + "password": "https://[domain.tld]" + } } } Use the ACF PRO license key as the username. The password should be the site host …

In your posted configuration, there is a tab missing for the site (mysite.com), and tabs/spaces are significant in YAML.
