New Obsidian update breaks functionality

[Hautemeal]

I just updated to the newest version of Obsidian (v0.13.14) and all my tracker pages are returning "Error parsing YAML".

Here's some examples of code I'm using that result in this issue:

searchType: frontmatter
searchTarget: anxiety
folder: 20 Daily Notes
startDate: -1w
datasetName: anxiety
line:
    title: Week
    yAxisLabel: Peak Anxiety
    yAxisUnit:
    lineColor: teal
	yMin: 0
    yMax: 10
	xAxisTickLabelFormat: ddd
	showLegend: false
	legendPosition: right
	legendBgColor: white
	lineWidth: 5
	pointColor: white

searchType: tag
searchTarget: mood/happy, mood/anxious, mood/high, mood/distracted, mood/accomplished, mood/excited, mood/frustrated, mood/nervous, mood/vibin
pie:
    title: Mood Pie
	data: '{{sum(dataset(0))}},{{sum(dataset(1))}},{{sum(dataset(2))}},{{sum(dataset(3))}},{{sum(dataset(4))}},{{sum(dataset(5))}},{{sum(dataset(6))}},{{sum(dataset(7))}},{{sum(dataset(8))}}'
	dataColor: 'green,red,blue,purple,teal,grey,orange,salmon,pink'
	label: Happy, Anxious, Chill, Distracted, Accomplished, Excited, Frustrated, Nervous, Vibin
	ratioInnerRadius: 0.5

I'm not very code-savvy, so I'm not really sure where to begin with diagnosing and resolving this issue myself. I don't use many add-ons, but the few I do use are up to date. Thanks in advance!

Also experiencing this issue, with tracker pages that worked mere hours ago

Found, at the very least, a temporary solution to this issue. By checking the developer console (CTRL-SHIFT-I), and looking into the error messages, it appears as though this error was popping up a lot "YAMLParseError: Tabs are not allowed as indentation at line 5, column 1:". So I changed my indentation from tabs to spaces, and now everything works as expected. Attached is a screenshot of the error in question.

[Hautemeal]

Wow. I can't believe that was the solution. Is this an Obsidian issue or Tracker issue?

[S1lentwanderer]

No idea. My guess is an Obsidian issue, since it worked in the previous version of Obsidian just fine, and the only thing that changed was the update. I'm not a developer though, just happened upon the console while trying to mess with CSS the other day, and thought to check it for this issue.

[Hautemeal]

Yeah...it does seem very odd. I guess someone is taking a hard stance on tabs vs spaces :P

Reported bug upstream on the Obsidian forum.

According to the YAML specs, a space is the only valid indentation method:

Chapter 6. Structural Productions
6.1. Indentation Spaces
In YAML block styles, structure is determined by indentation. In general, indentation is defined as a zero or more space characters at the start of a line.

To maintain portability, tab characters must not be used in indentation, since different systems treat tabs differently. Note that most modern editors may be configured so that pressing the tab key results in the insertion of an appropriate number of spaces.

The amount of indentation is a presentation detail and must not be used to convey content information.

Thanks for the additional info! That's useful to know :)

Obsidian tracker version 1.10.9 will replace the tab characters by spaces for you according to the tabSize settings in editor.
Will close this issue.

[Hautemeal]

Aww. That's such a sweet little quality of life improvement. Cheers!
