Not able to load .C image array under Arduino IDE environment

Description

Arduino IDE returns error message that not able to load .c image array converted from lvgl online tool.

What MCU/Processor/Board and compiler are you using?

ESP32 under Arduino IDE.

What do you experience?

I follow lvgl.pdf to convert the jpg image into .c image array online and included into program, I thought everything was followed the lvgl.pdf said. And I got below error:
indo_480_320_http.h:353:4: error: expected primary-expression before ‘.’ token
.header.always_zero = 0,
^
indo_480_320_http.h:354:4: error: expected primary-expression before ‘.’ token
.header.w = 480,
^
indo_480_320_http.h:355:4: error: expected primary-expression before ‘.’ token
.header.h = 320,
^
indo_480_320_http.h:357:4: error: expected primary-expression before ‘.’ token
.header.cf = LV_IMG_CF_INDEXED_4BIT,
^
exit status 1
expected primary-expression before ‘.’ token

The main problem seems happened in the const struct from .c file converted online,

const lv_img_dsc_t indo_480_320_http = {
.header.always_zero = 0,
.header.w = 480,
.header.h = 320,
.data_size = 76864,
.header.cf = LV_IMG_CF_INDEXED_4BIT,
.data = indo_480_320_http_map,

Having searched on internet, I found exactly the same issue : https://github.com/lvgl/lv_arduino/issues/41 Problem remains open.
