The bug
Unlike structure blocks, jigsaw blocks do not send any message saying a structure/piece was successfully loaded.
Steps to reproduce
Summon a jigsaw block with all of the necessary data already inputted in it and a grass block beside it by using the commands provided below.
/setblock ~1 ~ ~1 minecraft:jigsaw[orientation=north_up]{final_state:"minecraft:structure_void",joint:"rollable",name:"minecraft:building_entrance",pool:"minecraft:village/plains/houses",target:"minecraft:building_entrance"}
/setblock ~1 ~ ~ minecraft:grass_block
Open the jigsaw block and set the "Levels" value to "1" and then click the "Generate" button.
Notice how there is not success message upon the structure being generated.

Can confirm in 1.18.2 and 22w15a. For ease of reproducing this, simply execute the command provided below, set the "Levels" slider to 1, and hit the "Generate" button within the jigsaw block.
/setblock ~2 ~ ~ minecraft:jigsaw[orientation=north_up]{final_state:"minecraft:structure_void",joint:"rollable",name:"minecraft:building_entrance",pool:"minecraft:village/plains/houses",target:"minecraft:building_entrance"}
