ERROR! File: 'xxx' could not read check-marking'

[SqualeDev]

I've some problems when loading gcode files...
My GCode files is generated by CURA 5.5.0.

The loading file doesn't add the 'M117 INDICATOR-LayerX' so I've added manually.

There is the content of GCode file :

After ';LAYER:0', I've added 'M117 INDICATOR-Layer1' line and after each ';LAYER:X' lines but I've had this error in octoprint.log file :
