Pixl.js I2C not working correctly? I2C Write Error 33281

Hi.

I'm trying to get a BME280 working using I2C.

I can't seem to get it to work on my Pixl.js

Using the hardware I2C like this:

var BME = require("BME280");
I2C1.setup({scl:A5,sda:A4});
var bme = BME.connect(I2C1, { addr: 0x76 });
console.log(bme.getData());

I'm getting this error

Uncaught InternalError: I2C Write Error 33281
 atUncaught InternalError: I2C Write Error 33281
 at line 1 col 18
a.writeTo(c,[d,g])
               line 1 col 18
a.writeTo(c,[d,g])
                 ^
in function "write" called from line 1 col 4   ^

When i try to use software I2C, it kinda works, but only the first measurement and the humidity is wrong.

var BME = require("BME280");
var i2c = new I2C();
i2c.setup({scl:A5,sda:A4});
var bme = BME.connect(i2c, { addr: 0x76 });
console.log(bme.getData()); // logs { "temp": 24.00835012295, "pressure": 961.35353842504, "humidity": 84.1865234375 }

setInterval(function() {
  console.log(bme.getData()); // logs { "temp": -143.48718913660, "pressure": 1126.77476317288, "humidity": 0 }
}, 1000);

Thing is, it does work on my Espruino Pico using this code:

var BME = require("BME280");
I2C1.setup({scl:B8,sda:B9});
var bme = BME.connect(I2C1, { addr: 0x76 });
console.log(bme.getData());

This logs the correct humidity, works with hardware I2C and continues to work (in a setInterval for example).

I don't know what to do at this point. Is I2C just broken on (my) pixl.js?
