Thanks for the information! A wild guess (apologies for the noise if if there is an obvious reason why it can't work!): maybe it's worth trying replacing format={pdf/a-1b:2005}, with format={pdf/a-1a:2005}, or another supported format? (If I read the logs correctly, the supported formats are 2 | 2.0 | a1a2005 | a1b2005 | a2a | a2b | a2u | a3a | a3b | a3u | ua1 | ua2 | x1a2001 | x1a2003 | x32002 | x32003 | x4 | x4p | x5g | x5n | x5pg .)
