I can't reproduce using the command you've provided, as it does work correctly.

Dragonmcmx 2014-06-26T11:05:52Z

I've got the same problem. Any books with json data just output: * Invalid Book tag *

Skylinerw 2014-06-26T11:10:18Z

@Dragonmcmx - there are some requirements that must be fulfilled before it works. You must have both a book "title" and author", which cannot exceed 16 characters. This particular report fulfills those requirements, and copy/pasting the command directly works just fine with no errors.

Dragonmcmx 2014-06-26T20:15:04Z

@Skylinerw, I meet all those requirements and still get those errors. Even if i don't add any json data to the book, it still outputs * Invalid Book tag *.And the books did work perfectly in 14w25b, so yeah.

Skylinerw 2014-06-26T20:19:04Z

@Dragonmcmx - it would be better if you'd provide the exact command(s) you're using if this relates to the bug report.

Having this issue in 14w26c myself.

EDIT -
Although mine was related to 16 character title length... I wish that wasn't changed.

I can't get my awesome spell book because of this!!! It sucks and needs to be fixed.

Here is one of the commands I'm using:

/give @p written_book 1 0 {title:"Admin Command Book",author:dragonmcmx,pages:["{text:\"  Admin Commands\n\n\",color:dark_red,bold:true,extra:[{text:\"Gamemode Creative\n\",color:gold,bold:false,hoverEvent:{action:show_text,value:\"Hop into Creative Mode.\"},clickEvent:{action:run_command,value:\"/gamemode 1\"}},{text:\"Gamemode Survival\n\",color:dark_gray,bold:false,hoverEvent:{action:show_text,value:\"Hop into Survival Mode.\"},clickEvent:{action:run_command,value:\"/gamemode 0\"}},{text:\"Toggle Downfall\n\",color:dark_blue,bold:false,hoverEvent:{action:show_text,value:\"Toggle Rain/Snow.\"},clickEvent:{action:run_command,value:\"/toggledownfall\"}},{text:\"Clear Lag\n\",color:dark_green,bold:false,hoverEvent:{action:show_text,value:\"Remove Ground Items.\"},clickEvent:{action:run_command,value:\"/kill @e[type=Item]\"}},{text:\"Time Night\n\",color:black,bold:false,hoverEvent:{action:show_text,value:\"Set the Time to Midnight.\"},clickEvent:{action:run_command,value:\"/time set 18000\"}},{text:\"Time Day\n\",color:blue,bold:false,hoverEvent:{action:show_text,value:\"Set the Time to Midday.\"},clickEvent:{action:run_command,value:\"/time set 6000\"}}]}"]}

Worked perfectly in 14w25b, broken in 14w26b and 14w26c.

@dragonmcmx - Your title exceeds 16 characters, which was one of the requirements. Reduce the amount and it works fine.

Dragonmcmx 2014-06-27T19:43:50Z

@Skylinerw It does indeed. Strange, because just earlier today i tried a book with only the title: Test, and the author: test. And it did show invalid book tag as well. Thanks nonetheless.

Confirmed for 14w26c BUT PLEASE change the description to:
Books without tilte/author or too long title (>16) cause

Invalid book tag*

Actually the command you have in your description is working in 14w26c

Also this is created when the "pages:[]"-tag is missing

qmagnet 2014-07-06T19:44:37Z

I have a book in 14w27b with no title and it works fine. So I don't think author has anything to do with this bug.

marcono1234 2014-07-10T09:42:41Z

Confirmed for 14w28a
@qmagnet: Can't be, this ONLY affects books, that you give, probably not books that have been created in earlier versions.

Commands that cause invalid book tag:
No title

/give @p written_book 1 0 {author:"HI",pages:[]}

No author

/give @p written_book 1 0 {title:"HI",pages:[]}

No pages

/give @p written_book 1 0 {title:"HI",author:"Hi"}

Too long title

/give @p written_book 1 0 {title:"abcdefghijklmnopq",pages:[],author:"Hi"}

qmagnet 2014-07-10T13:29:50Z

I see. Strange. Tested. Stupid bug. Why would older books still work?

marcono1234 2014-07-15T19:47:12Z

Probably in earlier versions, Minecraft itself added the missing tags (at the too long title bug I don't know what happened) but somehow maybe because of the JSON function of books it got lost so Minecraft has "incomplete" books, however you can leave "resolved" tag away)

marcono1234 2015-11-17T17:38:00Z

Confirmed for

15w46a Probably does not become reopened anyway
