SDK Does not Pass the Typechecker

[dairyisscary]

What happened and what did you expect to happen?

The file node_modules/amazon-chime-sdk-js/build/signalingprotocol/SignalingProtocol.d.ts does not pass typescript typechecker. I have elided the output but there are 22 instances of this same error:

node_modules/amazon-chime-sdk-js/build/signalingprotocol/SignalingProtocol.d.ts:7:26 - error TS2709: Cannot use namespace 'Long' as a type.

7     timestampMs: (number|Long);
                           ~~~~

node_modules/amazon-chime-sdk-js/build/signalingprotocol/SignalingProtocol.d.ts:89:33 - error TS2709: Cannot use namespace 'Long' as a type.

89     public timestampMs: (number|Long);
                                   ~~~~

skipLibCheck is false in my project

I did a manual patch of SignalingProtocol.d.ts to change and it seems to compile

-import Long = require("long");
+import type Long from "long";

What typescript version are you using?

[dairyisscary]

As specificed in the original issue, this was produced in typescript version 5.3.3, though it still appears to be the case in 5.4.x.

I have made a minmalist reproduction with a replit here: https://replit.com/@dairyisscary/Aws-sdk-reproduction?v=1#tsconfig.json

i think that some combination of the tsconfig.json configuration options module, moduleResolution and of course, skipLibCheck: false are what make the semantics of this particular line import Long = require("long"); invalid here. 🤷
