Can't resolve member '${Array.isArray(path) ? path.join('.')

Error message

Can't resolve member '${Array.isArray(path) ? path.join('.') : path}'

What it means

This resolver iterates measures, dimensions, and segments via isInstanceOfType/byPath and throws a UserError when the path matches none of these member types. The cube and path format may be fine, but the member either doesn't exist or isn't a measure/dimension/segment.

Solutions

Verify the member exists as a measure, dimension, or segment in the cube/view
Fix typos in the member name after the dot
Check public:false / security filters aren't hiding the member from this context
Regenerate client schemas after schema changes

Example fix

// before
query.measures = ['Orders.notARealMeasure'];
// after
query.measures = ['Orders.totalAmount'];

Defensive patterns

Strategy: try-catch

Validate before calling

const { cubeEvaluator } = compilerApi;
const resolved = ['measures','dimensions','segments'].find(t => cubeEvaluator.isInstanceOfType(t, path));
if (!resolved) throw new Error(`'${path}' is not a measure, dimension or segment`);

Try / catch

try { return evaluator.resolveMember(path); } catch (e) { if (e.message.startsWith("Can't resolve member")) { /* inspect cube members for a close match */ } throw e; }

Prevention

Regenerate client schemas after model changes
Check public:/security visibility when members vanish
Validate measures/dimensions/segments lists against the compiled cube before querying

When it happens

Trigger: Calling cubeFromPath/memberFromPath/resolveMember with a valid 'Cube.name' path where name is not an existing measure, dimension, or segment — e.g. referencing a timeDimension-only pseudo member or a deleted measure.

Common situations: Stale client queries referencing renamed members; using a pre-aggregation or hierarchy name where a member is expected; typo in member name with correct cube; member filtered out by security context/public visibility.
