X-Amz-Credential malformed

[aefika]

I've managed to generate the preSigned Url and everything works fine until the evaporate.add method.

The error I have is:
Error parsing the X-Amz-Credential parameter; the Credential is mal-formed; expecting "/YYYYMMDD/REGION/SERVICE/aws4_request"

The request is sending this X-Amz-Credential: AKIAUVF2LZT742H7D4JP%2F20250224%2Fca-central-1%2Fs3%2Faws4_request

It is clear that the X-Amz-Credential is encoded but AWS is expecting clear text (with the slash /).
