I wanted to create a book with texts that suggests a command to the player when clicked. This is impossible and working as intended according to MC-70317 (yes, I am slightly protesting in this bug report.) To work around this restriction I created a book with text, that when clicked runs a tellraw command, with text that can be clicked, to suggest a command. Clicking on the text in the book will cause the singleplayer world to crash and exit to the multiplayer screen. The ultimate issue seems to be that the command ran is too long which causes the game to crash
Recreation steps:
Place a command block with the following command:
give @p written_book[ written_book_content={ title:"Admin settings", author:"tholleman", pages:[ '[ { "text":"Change spectator duration", "underlined":true, "clickEvent":{ "action":"run_command", "value":\'/tellraw @s [ "", { "text":"Change spectator duration", "underlined":true, "color":"yellow", "hoverEvent":{ "action":"show_text", "contents":[{"text":"click me"}] }, "clickEvent":{ "action":"suggest_command", "value":"/scoreboard players set duration out_of_body.settings " } } ]\' } } ]' ] }]
Now activate the command block, open the book, and click the text.
This will result in a crash with the following stack trace in the log:
