Web IDE stopped pulling online modules?

Somehow Web IDE just stopped pulling modules from the online source, so I couldn't use any of the not integrated ones. On any module I try to require, it says "ERROR: Unable to mount SD card : NOT_READY \n WARNING: Module "xyz" not found" (I tried with module "PN532" and "KeyPad") and I don't know what to do. Even the Firmware update notification stuff working, so it couldn't be a network issue, the module link is correct in settings, and everything seems well, but still it doesn't work.

Can anyone help me, please?

Modules are only loaded when you send from right side of the web ide (since otherwise you're interacting directly with the espruino). Is that it?

I'm not sure what to suggest - is it possible that you've somehow modified the settings?

Under Communications:

• Module URL should be http://www.espruino.com/modules
• Module Extentions should be .min.js|.js

You could try installing the Web IDE manually from https://github.com/espruino/EspruinoWebIDE. When you do that, you can the use the Chrome Debugging tools to get a log window where you might be able to see what's going on.

Thank you for your reply, yep, I was dumb on this, the module loaded well (I guess) when sent from the right side - just thought the error was the same, but now another thing came up, and that occured first. I have the PN532, and when I connect it and want to run this code:

I2C1.setup({scl:B6, sda:B7});
var nfc = require("PN532").connect(I2C1);
nfc.SAMConfig(); // Start listening
console.log(nfc.getVersion());

this happening:

Uncaught Error: Field or method does not already exist, and can't create it on Uint8Array
 at line 1 col 288
...this.i2c.readFrom(36,d+1),b.slice(6)}
                               ^
in function "cmd" called from line 1 col 31
{return this.cmd([20,1,20,0],8)}
                               ^

                               ^
in function "getVersion" called from line 1 col 28
console.log(nfc.getVersion());

Before the firmware update it had worked, didn't even touched it for a long time after it worked.
Any guess? :/

Ahh - thanks. Sorry, this was because the new firmware sends back the (more efficient) Typed Arrays from I2C, and I hadn't tested it with the NFC module.

I'll fix this now and will get back to you in an hour or so (I need to do a new firmware release anyway).

Thank you :) Great support you provide I have to say.

Ok, fixed. You can get one of the 'cutting edge' builds from here: http://www.espruino.com/binaries/git/commits/15258560d35c23a6ed1ae8ba4b3089bf26aa58ba/

See http://www.espruino.com/Download for how to use them...

You probably guessed but the NFC module was using Array.slice, which works on Arrays, but not on Typed Arrays (in the ES5 standard). The not-released-yet ES6 standard does have slice on Typed Arrays though, so I just added that.
