Error when tokenizing the input source
Variants§
UnknownCharacter(char)
An unknown character was found
Unknown characters are characters that do not occur anywhere in the
GraphQL language, such as ?
or %
.
UnexpectedCharacter(char)
An unexpected character was found
Unexpected characters are characters that do exist in the GraphQL language, but is not expected at the current position in the document.
UnterminatedString
An unterminated string literal was found
Apart from forgetting the ending "
, terminating a string within a
Unicode escape sequence or having a line break in the string also
causes this error.
UnknownCharacterInString(char)
An unknown character in a string literal was found
This occurs when an invalid source character is found in a string literal, such as ASCII control characters.
UnknownEscapeSequence(String)
An unknown escape sequence in a string literal was found
Only a limited set of escape sequences are supported, this is emitted
when e.g. "\l"
is parsed.
UnexpectedEndOfFile
The input source was unexpectedly terminated
Emitted when the current token requires a succeeding character, but
the source has reached EOF. Emitted when scanning e.g. "1."
.
InvalidNumber
An invalid number literal was found
