JSON syntax error at line {0}, column {1} (character {2}) JSON syntax error {0}: expected ''{1}'' but found ''{2}''. {0}: expected number but found ''{1}''. {0}: expected number but found end of text. {0}: expected quoted name but found ''{1}''. {0}: expected '':'' but found ''{1}''. {0}: expected value but found ''{1}''. {0}: expected quoted name or ''}'' but found ''{1}''. {0}: expected '','' or ''{1}'' but found ''{2}''. {0}: expected quoted name or ''}'' but found end of text. {0}: expected '','' or '']'' but found ''{1}''. {0}: expected '','' or '']'' but found end of text. {0}: expected '':'' but found end of text. {0}: expected quoted name but found end of text. {0}: expected value but found end of text. {0}: expected '','' or ''{1}'' but found end of text. {0}: expected ''"'' but found end of text. {0}: escape character ''{1}'' is not valid. {0}: unexpected control character {1}. {0}: extra text. Unable to encode objects of class {0} as JSON-formatted text. Unable to encode objects of class containers.Map as JSON-formatted text. KeyType must be char. Unable to encode objects of class {0} because the structure is recursive. Max recursion limit of {0} reached. JSON text must be a character vector or a scalar non-missing string. Name ''{0}'' requires a value. Name argument type must be string scalar or character vector. Value type must be {0} scalar for name ''{1}''. Name argument must be ''ConvertInfAndNaN'' or ''PrettyPrint''. The jsonencode method implemented by the class author must return either a character vector or string scalar.
