Error compiling example with LVGL version 9.1.0

[vinny-888]

When I try to compile the chat_gpt example I get an error which seems to be due to the LVGL version

/git/esp-box/examples/chatgpt_demo/factory_nvs/main/ui/images/ui_img_setup_text_bg_png.c:1217:13: error: 'lv_image_header_t' has no member named 'always_zero'
 1217 |     .header.always_zero = 0,
      |             ^~~~~~~~~~~

 1221 |     .header.cf = LV_IMG_CF_TRUE_COLOR_ALPHA,
      |                  ^~~~~~~~~~~~~~~~~~~~~~~~~~
ninja: build stopped: subcommand failed.

I see at the top of the file in the error this LVGL version: 8.3.4

When I check my dependencies.lock I see

  lvgl/lvgl:
    component_hash: 2a8f619b5c2b1c7ad116c33d43dae8989c76739068f406a7e8ba9221e1085f17
    source:
      service_url: https://api.components.espressif.com/
      type: service
    version: 9.1.0

I cannot seem to find any info on how to change the LVGL version tho.

Any help much appreciated

Ok this seems to have fixed it in case anyone else runs into it

idf.py add-dependency "lvgl/lvgl^8.3.4"
