Flowcode Support Board

hi everybody

I try to send a byte to the I2C port expander with the PCF8574 component, but I always get an error when compiling. Reading port works normally but write port cant compile.
Flowcode "https://ibb.co/845k9dY" compiler error
"
Employing 18F4550 errata work-arounds:
* Corrupted fast interrupt shadow registers
v10bwr.c: FCD_02c31_PCF8574__WritePort()
200: FCD_05bd1_dash_IO_flasher1__FlashTx();
^ (361) function declared implicit int (warning)
using updated 32-bit floating-point libraries; improved accuracy might increase code size
0: (499) undefined symbol:
_FCD_05bd1_dash_IO_flasher1__FlashTx(v10bwr.obj)
(908) exit status = 1
(908) exit status = 1
"

please help thanks in advance
