Content Length

The declared length is checked against the JSON body bytes.

highlighted = computed this step

Content-Length declares the body byte count

The header declares 17 body bytes.

Content-Length=17\text{Content-Length}=17

The body count is recomputed

Counting the body bytes also gives 17.

The counts match

The check row says yes because the declared count and counted body length are the same.
