Bug: Shopify OAuth connection succeeds but Connect SDK reports empty error {}

[wenlongbrother]

Summary

When using the Pipedream Connect SDK (@pipedream/sdk, version is 2.3.1) with the Shopify oauth app integration, the OAuth flow completes successfully — the connected account is actually created in Pipedream — but the Connect popup reports an error and triggers onError with an empty error message.

This leads to a misleading UX where the connection appears to have “failed,” even though it succeeded internally.

Observe:

The Shopify account appears in connected accounts after refreshing. ✅

But the Connect popup shows red banner:
“Connection failed. Please retry or contact support”. ❌

The error object received by SDK is:

{
  message: "",
  raw: "{}"
}

Network trace shows Pipedream connect.html iframe sends { type: "error", error: "" }

Expected Behavior

After successful OAuth and connection creation,
onSuccess should be triggered and no error should be emitted.

onError should not fire with empty {} error when the account is created successfully.

Hi @tjk @jverce , tagging you since we found you’ve recently worked on the SDK .
Could you please help review if this bug exist in SDK? Thanks
