Base64URL missing padding: how to normalize '=' safely
Base64URL missing padding: how to normalize '=' safely: normalize '-'/'_', add '=' padding, then decode/convert safely with local tools (no upload).
Missing Base64 padding
Fix Missing Base64 padding. Validate the encoding variant (Base64/Base64URL/URL encoding), then decode safely without uploading tokens or payloads.
TL;DR: Validate locally, pinpoint the failing spot, apply the minimal fix, then validate again.
Fast no-upload workflow
- Validate the input (strict rules, correct encoding, correct delimiter/quotes).
- Locate the exact position/line reported by the parser or validator.
- Fix the smallest broken part (often a quote, escape, delimiter, or a truncated copy/paste).
- Re-validate and only then convert/export.
