[BUG] Switched to Marlin 2.x. File upload via WebUI, results in empty uploaded file, but...

[MAGIC-SM0KE]

FW version:1.0 # FW target:marlin # FW HW:Serial SD # primary sd:/sd/ # secondary sd:/ext/ # authentication:no

File uploaded via WebUI, using menu on the right, result in empty uploaded file.
However, from command terminal :
M110 N0
N1 M28 hello.g19
N2 M117 hi there73
N3 M300 P400 S50033
N4 M2928

results with successfully uploaded file hello.g (size 31b)

I've been using EPS3D 1.0 on ESP8266 1Mb, since 2018. Everything worked fine, with Marlin 1.1.9 (8-bit Melzi board). Recently, i switched to SKR 1.3 and SKR 1.3 mini (Marlin 2.x) and this problem appeared.

On Marlin Repository
they mentioned something about a change in M28 functionality, in Marlin 2.0.X

Is this a known problem ? How should i resolve this ?

Thanks

ESP3D 1.0 won't work well with Marlin 2.0 need to use ESP3D 2.1 and ESP3D-WEBUI 2.1 which has several fixes for Marlin 2.0

I flashed 2.1 and now, it works great!
Thanks

Actually I've got the same problem (UI: 2.1b20 / FW: 2.1.0.b39) on a ESP12F. I've got a Marlin 2.0, which is customized for the SapphirePro (https://github.com/inib/Marlin/tree/2.0.X-SapphirePro-3.5TFT). Manual creation of a file in UI works as described by MAGIC-SM0KE. I tried different sd cards, baud rates, browsers. The result is always a 0 byte file.
