I think this line

plotly.js/src/lib/index.js

Line 1159 in b5f0316

return v || v === 0;

should be

return v || v === '' || v === 0;

OR this line:

plotly.js/src/lib/index.js

Line 1051 in b5f0316

if(value) getterCache[key] = value;

@etpinard The function templateFormatString actually consider empty string a valid value:

plotly.js/src/lib/index.js

Lines 1044 to 1047 in b5f0316

	if(obj.hasOwnProperty(key)) {
	value = obj[key];
	break;
	}

The change proposed by @archmoj in #4173 (comment) fixes the issue. Hopefully, it doesn't break anything else. Unfortunately, it does break other things.

Ok, but I would prefer not rendering <text> elements associated with '' strings.

@archmoj It doesn't seem like the issue lies with the texttemplate routine itself but rather in how sunburst calls it.

Did you encounter this error with other traces than sunburst?

This commit 9b4a38d should flag the traces other than sunburst for which this issue exists!

[antoinerg]

Ok so here are the traces affected:

• pie
• funnelarea
• sunburst
