Unclear The finding does not say where the new helper is used.
What
A new helper sorts server error responses. It treats status codes in the 400s as one group, except for these three:
- 408, a timeout
- 409, a conflict
- 429, too many requests
New helpers that read environment variables were also added. They strip spaces from the start and end of each value.
Why
Errors that retrying will not fix can be told apart from ones that may succeed on a second try.
