Last version - Invalid arg2 on read

[FerX]

Raspberry PI Zero

with update to the latest version, when I send the read command I get this error.
before, it worked fine

       return bindfunc(arg1, arg2);
               ^

Im getting the same thing. Huge, Huge problem for me!!

Rolled back to version 2.2.0 and working again. Wonder what is going on with this library?? It has been rock solid for years! Just an FYI if anyone cares. Version 2.4.0 caused my Pi Zero to pretty much brick itself. Thank god I caught it before it got pushed out to my other devices in the field. I hope others are lucky too.

Oops, I'm really sorry. I've been running the latest code on a number of devices, but none of them use the read() method so I didn't notice.

This should fix the problem, can you verify?

I've pushed version 2.4.1 to fix this, sorry again for the breakage.

[JohnRucker]

I updated to 2.4.1 and pushed it to my test machine. Getting a new error now looks like in line 892 of rpio.js. Rolled back to 2.2.0 and everything is working again. Thanks for getting on this so quick sorry I didn't test it sooner.

Gah, stupid mistake copying the change from my test host. Sorry, this is really poor of me, fixing now.

[jperkin]

I just published version 2.4.2 which should fix this. Really sorry again, I need to sit down and finish off the migration from Travis CI so that I get automated tests back up and running again to catch stuff like this (as well as not rushing to fix breakages and introducing more breakages...)

[JohnRucker]

2.4.2 Looks great! Thanks again for getting on this so quick. Don't be so hard on yourself! You do fantastic work my friend!!
