ERROR Invalid syntax (UIFlow 1.6.2) when trying to upload
Hi and thanks,
Indeed I use (and prefer to use) the desktop version, but I gave it a go with the online version. A similar thing occurs, I can run it, but now it hangs when trying to upload to the device, showing the "Uploading..." indicator on the core screen...

It’s usually quick, but sometimes downloading your flow to the device takes a bit (~1 minute). Send or PM me a link to the file and I’ll give it a try.

Also, the Desktop uiFlow IDE is several revs behind the web version. I hope they will keep both IDEs in feature parity in the future.
Hi, I left it "uploading" for about 15mins, long enough to conclude it hangs I suppose.
You can find the m5f file here
(Bear in mind, I'm no coder, just a hobbyist)

Download (or upload to the device) worked for me. However, it took several tries for my device to stay connected to the uiFlow web IDE. I kept having to hit the refresh button and I rebooted my m5stack once.
Stability of the web IDE can vary, depending on your location, time of day, and how many people are using the server. But overall, I didn't have a problem with our flow and it loaded onto the device in about 10-15 seconds.
If you still can't get it, you could switch to the Python tab and copy all the Python code to a file called main.py on your computer. Then use ampy, Thonny, Mu, or another utility to copy main.py to your device and place it in the /flash directory. Then the m5stack should boot your program by default after startup.
Hi, thanks for having a go at it.
As I mentioned before, with the desktop version the python file gets uploaded, but then I get the syntax error (when it should auto-start after the upload). After a manual reset and switch to app mode, the python file is on the device, I can select and run it on the core, it runs fine. I can run the py from and upload it via Thonny too without any problem. I've tried it on 2 devices, a black and a grey, I've tried different cables all with the same result.
With other projects the upload to the device also works fine. Is it because there something wrong with my .m5f ? Is it because its a little bigger, who can tell ? I really would like to have this issue solved before I officially share this project so people -especially new to m5stack- can atleast get it up and running without hassle.
Wel this problem still persists, I guess I was secretly hoping for someone from m5stack to shed a light on this matter. ;-)
Is there maybe someone who could try to reproduce this error with the desktop version of UIFlow ?
So I managed to get UIFlow running on a linux machine (a struggle in itself, I dare say) and... same result, it hangs while uploading via USB. It doesn't give me the syntax error, but it's stuck with the "Uploading..." indicator diplayed on the device.

@ardo thank you feedback. i had test your program (m5f file) , got the same stuation in the offline version UIFlow 。 (the online version UIFlow is not problem. ） we will fix this bug as soon as possible.
FW1.6.4 and editor 1.0.12 totally broke my program, still can't upload but then again, why would I need to, it doesn't even run anymore, the python code gets screwed up.
I don't get to make an app anymore, all I do is running into stuff that doesn't work. It seems to me M5stack is suffering from what I call the "Yamaha disease" : keep spitting out new hardware without fixing the mediocre stuff they released before.
Well I for one am not jumping on that train anymore , I refrain from buying any more new stuff a la core2 and whatnot before the existing stuff gets fixed. (which I expect now, will never happen)
