Github Auth token not working in auth.json file Magento 2.4.2

Question

I have my project in magento 2.3.3 and I am upgrading it to Magento 2.4.2. In auth.json file I want to add github token generated from the link https://github.com/settings/tokens/new?scopes=repo&description=Composer+on+NTZ-CPU-155+2021-04-09+1517. But the token is not working when I am adding the same in mu auth.json file.

Error I am getting:

Your github oauth token for github.com contains invalid characters: "ghp_1nKdhaeIbUzRN2DsrMDkB2kbLXzFcn0jwjhdwhaQyEt"

Answer 1

As mentioned in "Authentication token format updates are generally available", the format of GitHub authentication tokens has changed.

Notably, the token formats now include the following updates:

• The character set changed from [a-f0-9] to [A-Za-z0-9_]
• The format now includes a prefix for each token type, including ghp_ for Personal Access Tokens.

That is why composer has issue 9800: "Please release a version with updated GitHub token regex"

The resolution is to upgrade composer to 2.0.12 and 1.10.21, which include commit dc83ba9.

 # old regexp
 {^[.a-z0-9]+$}

 # new one
 {^[.A-Za-z0-9_]+$}
