无效的JWT格式

Error message

无效的JWT格式

What it means

Format guard in decodeJWTURL: the token does not start with http(s) and does not split on '.' into exactly 3 segments (header.payload.signature). Input at fault is the Button.URL value from susu — it is not a JWT at all.

Solutions

1. Check what susu actually returned in Button.URL
2. Handle 2-segment or otherwise-shaped tokens if the site changed format
3. Fail per-link, not per-search

When it happens
