Description

The content of share URL for particular session is blank, but other sessions are good. Suspect the reason could be the session is too long which is larger then the server limit.

Detail: Server-side streaming SSR response is incomplete, the getShareData Promise never resolves.

Plugins

No response

OpenCode version

1.1.25

Steps to reproduce

No response

Screenshot and/or share link

Same issue here. Session ses_405d0df22ffezHHApMkehF6jhK with 1274 messages + 5059 parts (6300+ items total).

Share URL: https://opncd.ai/share/kehF6jhK

Console error:

Error: Too many subrequests.
    at AwsClient.fetch (placeholder:23730:27)
    at async Object.read (placeholder:23933:30)
    at async Object.read (placeholder:24014:24)
    at async placeholder:24177:69
    at async Promise.all (index 997)
    at async Object.data (placeholder:24177:25)

The Promise.all in Share.data() fires one Storage.read() (→ AwsClient.fetch) per event, which exceeds Cloudflare's per-request subrequest limit (~50 for Workers, ~1000 for Durable Objects) when there are many events.

Root cause (from packages/enterprise/src/core/share.ts):

const data = await Promise.all(
  list.map(async (event) => await Storage.read<Data[]>(event))
).then((x) => x.flat())

This fans out to N R2 reads in parallel. For large sessions, N easily exceeds the subrequest cap.

Possible fix: Paginate the event reads or eagerly compact events during sync() instead of deferring all compaction to read time.
