Uncaught TypeError: Cannot read property 'join' of undefined

[serapath]

I'm doing const url = 'dat://c610858d82e4c9bc9585bb26fedb260c080ed24c6a05bcf3da9ad73a6917ac82/' const archive = Hyperdrive(url)

using version "dat-sdk": "^0.1.0"

getting the following error:

What sort of build tools are you using? Browserify?

[ninabreznik]

[serapath]

yes, browserify. see https://github.com/ethereum-play/smartcontract.codes

we refactored the code inside out and currently it looks like it all breaks when execution reaches:

const url = 'dat://c610858d82e4c9bc9585bb26fedb260c080ed24c6a05bcf3da9ad73a6917ac82/'

const archive = Hyperdrive(url)

[serapath]

some of our test users also got:

Could not connect to local gateway at ws://localhost:3472,
trying remote gateway at wss://discoveryswarm.mauve.moe.
This isn't an error unless you're trying to use a local gateway. 😁
DOMException: "The operation is insecure."

... i think we have quite a lot of users who try to open the page in incognito. Maybe there is way to store stuff in the browser, so maybe in that case - is it possible to throw an error that i can catch so then we can

• based on that error try again, but tell dat-sdk to just store stuff in memory.
• also we could first tell the user the incognito problem and let them decide

[RangerMauve]

I'm not sure how to get that join error. I tried loading it in Chrome and Firefox and it seemed to be working. I tried in incognito mode as well. 🤔 Is the error causing code deployed to the website?

I think you'll need to add some code to detect when people are in incognito mode and add persist: false to the archive.

By the way this looks really cool! I love the color scheme and layout. 🤩

[RangerMauve]

I don't think this is an error with the gateway though. 🤔

[RangerMauve]

So, as we discussed on IRC, it seems to be an issue introduced in a fix I submitted to hyperdrive a week or so ago.

It fixed an issue on Windows, but introduce an issue on web since browserify's path implementation doesn't supply the path.posix property.

[RangerMauve]

This should be fixed in version 0.2.0 😁

[ninabreznik]

Is 0.2.0 out? We for now installed the verison of Hyperdrive you recommended and it works fine!

Yeah! I just released it. 😁 It should work with the latest hyperdrive (9.16.0).

[ninabreznik]

Sweet. Will try to update and see how it behaves. Thanks :)
