Can confirm in 1.18.2 and 22w15a. To more easily reproduce this so that you don't have to input anything into the jigsaw block, you can simply execute the following command and press the "Generate" button within the block.
/setblock ~2 ~ ~ minecraft:jigsaw{final_state:"minecraft:air",joint:"rollable",name:"minecraft:streets",pool:"minecraft:nonexistent_pool",target:"minecraft:streets"}
Can confirm in 20w51a.
