Hello,
I did the #build ....schema

command and then he started build my construction. But at a time he is telling me that the material is missing but I got it inmy inventory and in my Hand. i switched to survival but its the same issue. I tried differrent settings etc. but nothing helps.

try #buildIgnorProperties has_book,powered
if that still doesnt solve the issue also try #buildIgnoreDirecton true
if that still doesnt work use #buildSkipBlocks lectern to completely skip lecterns

Ok the commands are pastedt but the problem isnt solved

still the same one

1st Command wasnt dound. i copied and pasted it: #buildIgnorProperties has_book,powered

same with the seccond command

this settings is relatively new what version of baritone are you using?

It’s misspelled. Should be buildIgnoreProperties

Null Version

I did all commands also the last one with #buildSkipBlocks lectern normal it should skip the lectern but he is telling me the same that the material isnt availble

after you applied the settings did you restart the build process?

yes

i think this is a duplicate of #3931 and its already fixed in 1.12 by #3936

Right. Will be fixed in the next release (there's hope this will be soon!).
