Looks like lots of failing tests from CI, so this fix may not be as simple as we thought it was. |
…tPropertyOfType` e350c35 (microsoft#40228) introduced a subtle bug: it switched the flags to an alias, dropping `SymbolFlags.Property` --- and that makes `symbolIsValue()` get to the `resolveAlias(symbol)` call, which leads to `getPropertyOfType()` with`resolved.callSignatures`+`constructSignatures` being `undefined`. So initialize them in `setStructuredTypeMembers` before calling `getNamedMembers()`. Fixes microsoft#42350

This didn’t make it into 4.2. I’m assuming that was unintentional, since the bug was milestoned as 4.2.1? /cc @DanielRosenwasser @typescript-bot cherry-pick this to release-4.2 |
