[BUG]: LangChain ESM support broken for @langchain/core@>=1.0.0 #6826
Description
Tracer Version(s)
5.75.0
Node.js Version(s)
22.17.0
Bug Report
Leaving this as a community notice while I work out a solution, since I haven't seen a report yet. From our test version dependabot update, and running tests locally, it looks like the most recent major release of LangChain is not compatible with dd-trace (no errors produced, just missing spans as a result of incompatible instrumentation). A fix has been identified and we're working on implementing it. This should not affect CommonJS applications using LangChain
