Leading Zero in URL Query Causes Error

Thanks for reporting this. From the IS is not clear though what happens, what the undesired outcome is.

Thought: Try quotes around the token.

The given module is using YAML parser to parse the token. Till Symfony 5.0 version, YAML 1.1 specifications were used which was converting strings starting with 0 to octal numbers and strings starting with 0x to hexadecimal numbers. From Symfony 5.1 onwards, the representation of the octal number changed to "0o..." and that will fix the issue mentioned here.

So, we have 2 options here:

1. Upgrade to Drupal 10 as it uses a higher version of Symfony (not possible for all web projects and needs more efforts)
2. While using a token in field config, enclose it in quotes as mentioned in comment #3 🐛 Leading Zero in URL Query Causes Error Active to fix the issue.
