<![CDATA[ERROR Invalid syntax (UIFlow 1.6.2) when trying to upload]]>When I try to upload my project i get this error:
X ERROR Invalid syntax
Detail: File '<string>', line1 Syntaxerror: invalid syntax (quite explanatory, isn't it :)

My project runs fine from UIFlow and It does upload the python file, I can select and run it from the core

I've been searching around here but only found this post but it did not provide a solution.

Could this be a bug or is my project messed up or something else ?

UIFLow version 1.0.11 FW1.6.2 on win10 64

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)

It doesn't give me the syntax error, but it's stuck with the "Uploading..." indicator diplayed on the device.

Is there maybe someone who could try to reproduce this error with the desktop version of UIFlow ?

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.

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, 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)

I hope they will keep both IDEs in feature parity in the future.

Send or PM me a link to the file and I’ll give it a try.

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...

Are you using the offline/Desktop version of uiFlow? If so, can you try the web IDE https://flow.m5stack.com to see if you get the same error?
