MARKLESS_SHARED_MEMBER_UNKNOWN
Shared state has no such member: a Markless compiler error.
Error from the compiler, while it builds your .tsrx files.
What happened
Markless prints the message, the reason, and a suggestion:
MARKLESS_SHARED_MEMBER_UNKNOWN: Cannot read "<source>" because the <definitionName>() shared state declares no member named "<member>".
A member read is lowered into a path subscription on a declared graph node. A path the node never declares reads undefined on every render and after resume, so the code that depends on it silently does nothing.
Declare "<member>" in the state() initial value of <definitionName>(), or read a member the definition already declares.
