BatchExporter not working on nextjs/vercel/otel

[pksorensen]

Hi,

I made a small repo https://github.com/pksorensen/nextjs-repro-otel/tree/bugs/batchprocessor related to another issue and found additional issues that i am unsure where to report/solve.

vercel/next.js#67737

I found out that when using batchprocessor is used over simpleprocesor , then no spans are exported when it is on the edge runtime (was testing opentelemetry from Middleware ).

in instrumentation try to change from batch to simple and it works as expected (you see spans in console) and with batch you dont.

I don't believe this is an issue with this library, as I had issues with BatchSpanProcessor before I even tried using this. From what I can tell, the implementation of that processor is a little buggy. You might have better luck reporting this on the main OpenTelemetry repo for JavaScript. BatchSpanProcessor isn't something Vercel implemented or probably even maintains.
