Unexpected TypeError since upgrading to 2 but I do not know why it happens

[RussBaz]

I have started encountering an unexpected error that does not seem to affect much in my code since upgrading to HTMX 2.0 on some pages:

[Error] TypeError: null is not an object (evaluating 'o.includes')
	ft (htmx.min.js:1:20183)
	Pt (htmx.min.js:1:25992)
	(anonymous function) (htmx.min.js:1:26270)
	se (htmx.min.js:1:5323)
	kt (htmx.min.js:1:26249)
	(anonymous function) (htmx.min.js:1:11883)
	(anonymous function) (htmx.min.js:1:15957)
	se (htmx.min.js:1:5323)
	c (htmx.min.js:1:15930)

Does anyone know where it is coming from?

Thanks!

Hey, could you try with the unminified htmx script to be able to identify which line of code triggers this error ?
Also, if you're able to track down the situation causing the issue and provide a reproducible example, it'd greatly help!

Just tried and found this error message (did not have time to confirm the cause, however):

We hit a similar error and for us it was forms with no explicit "action" attribute. It doesn't have to have a value, so you can do action='', but it needs to be on the form tag. Or you can set boost to false.

looks like the issue is related to a recent change in #2802

look like the case where action is not defined may now not be handled well???

i think it should read

if (verb === 'get' && path && path.includes('?')) {

So it will ignore the if when path is not defined.
