I used "DecompilerMC" from GitHub to decompile the source code for Minecraft 1.17 to learn what trades could possibly had the villagers and how did they mechanics worked when I found several words that looked like they were wrong. The words I found were these:

• "SuspisciousStewForEmerald()" instead of "SuspiciousStewForEmerald()" (one "s" less).

- "Items.GLOBE_BANNER_PATTER" instead of "Items.GLOBE_BANNER_PATTERN" (one "n" more).

The affected file was at "...\client\net\minecraft\world\entity\npc\VillagerTrades.java", but perhaps some other files were affected too. It's not a big bug, but I believe that those words were not intended like that. Thanks a lot and have a nice day
