TypeError: Invalid value used as weak map key
Closed this issue · 20 comments
Hey there Sunil,
After uprading to 2.20.13, I'm getting this error
TypeError: Invalid value used as weak map key
on load of my site.
Any clue?
Damn I wish I had some sample css for you, its hard to parse given my Meteorjs errors. Let me look and ill get back to you.
Let me verify this brb!
None of my css calls are doing straight up strings. But my webpack devtools arent being too helpful at eval
any ideas to help you out?
on it
I published 2.20.16 with a try/catch for the above error, and it logs the arguments to console at least once. Give it a spin and lemme know, if it fixes your issue, and what it spits out to console for this error.
Yo sunil, you were right, it was a css fuck up in another module we have
failed setting the WeakMap cache for args: data-css-wn814s: ""
this should NOT happen, please file a bug on the github repo.
Thanks so much for putting this log in here. I was wondering if we could do this for any error generated by Glamor? often times its my own doing, but it would be nice to know what blew up since my app is humungous
Damn, we have a bunch of these in our app. I wonder if the aphrodite shim people have these
foo ? css(bar) : ''
cause i believe null
in aphrodite's css
blows up
ok, I think I know what's going on, it's quite subtle. Gimme a day or so and I'll fix this.
your current workaround should be to avoid sending those strings.
Yeah what Im saying is null/undefined did not work in aphrodite
unless im mistaken. So we had tons of code just returning empty strings. Thus causing this error when we did a sweeping change to use glamor/aphrodite.
Resolving the ternaries to null works out fine for us, just tons of those to go through. Let me know if you need anything else
I got in a fix for you, live in 2.20.19. lemme know if it works.
Thanks a lot Sunil. will check this out today! Appreciate the speed!
You'll appreciate the speed of the new release more :P The aphrodite shim goes very well with the new WeakMap caches, so your app should get faster for free. Lemme know!
closing this, lemme know if the issue persists. cheers.
