it's due to the fact that this sensors needs to stabilize before fetching, previously it was implemented in the main as:
/* Wait for sensors to stabilize */
k_sleep(K_MSEC(SENSORS_WARMUP_DELAY_MS));
with warmup delay equal to 5 seconds, after which sensors where initialized.
First 3 fetching of ccs811 data fails:

Warmup was removed in PR: #15 causing described bug.
