Error after 5.4.0 upgrade in decodebase64[]

Developers

Folks,

I just upgraded my private BlogToSelf wiki, which admittedly includes a lot of hacks, to 5.4.0 and I get the following error and I am not sure where to start debugging?

Internal JavaScript Error (Edge)

Uncaught InvalidCharacterError: Failed to execute ‘atob’ on ‘Window’: The string to be decoded is not correctly encoded.

Some guidance on investigating this would be appreciated.

In firefox I get a simpler message

Internal JavaScript Error (Firefox)

InvalidCharacterError: String contains an invalid character

In Both cases I loose control of the user interface, and although I saw a save triggered I seem not to have any other control.

[Edit1] Loading the wiki with a #not not existing tiddler loads without error, but as soon as I select any tiddler or save a new one I get the error.

  • As I have a sophisticated subtitle I removed the $:/tags/ViewTemplate from $:/core/ui/ViewTemplate/subtitle and it is no longer being triggered.

[Edit2] Its at times like this I wish I had shortcuts to assist with toggling tags and other support for debugging by elimination.

I’m glad you were able to isolate the problem tiddler! If the bug seems to be related to your $:/core/ui/ViewTemplate/subtitle modifications, it might be useful to share the text content here. Someone may be able to identify the specific character(s) giving 5.4.0 trouble.

Yes I built a tool to toggle tiddlers with the $:/tags/ViewTemplate/Subtitle to $:/tags/ViewTemplate/Subtitle-disable then toggled them back one after the other, eventually a tiddler containing the following caused the failure;

{{{  [all[current]get[created]format:date[YYYY/0MM/0DD hh:mm]] }}} - {{{  [all[current]get[created]format:date[YYYY0MM0DD0hh0mm0ss0XXX]]}}} - {{{  [all[current]get[created]format:date[YYYY0MM0DD0hh0mm0ss0XXX]decodebase64[]encodebase64[]]}}}

A quick process of elimination shows the following causing the problem;

{{{  [all[current]get[created]format:date[YYYY0MM0DD0hh0mm0ss0XXX]decodebase64[]encodebase64[]]}}}

And removing the decodebase64 stops the error.

Since this was but an experiment I have deleted it however I have confirmed the following in a tiddler on tiddlywiki.com replicates this problem;

{{{  [all[current]get[created]format:date[YYYY0MM0DD0hh0mm0ss0XXX]decodebase64[]]}}}

So the problem is solved for me but not for the decodebase64[] operator on 5.4.0 which may need to be addressed in 5.4.1

Can you create an issue at GitHub, with your last message. It will be easier to track there.
