plugin install can hang or hit proxy.url errors when HTTP_PROXY/HTTPS_PROXY are set #31319

Description

When HTTP_PROXY / HTTPS_PROXY are set, opencode plugin --global ... can hang for a long time during Installing plugin package, and some runs eventually end with:

fetch() proxy.url must be a non-empty string

If I unset only HTTP_PROXY / HTTPS_PROXY, the same plugin install succeeds quickly. This is true even when my system TUN mode is enabled, so the problem appears to be in the explicit proxy-env code path rather than general network reachability.

From the current source tree, plugin install goes through @npmcli/arborist in packages/core/src/npm.ts, not opencode's own fetch path.

The more important source-level finding is that the repo contains an @npmcli/agent patch intended to stringify proxy.url:

• patches/@npmcli%[email protected]

but the workspace currently locks:

• @npmcli/[email protected] in bun.lock

and patchedDependencies is version-pinned, so the patch is not applied to the resolved version.

That looks like a strong candidate for the proxy-specific install failures/timeouts.

Plugins

Reproduced with:

• opencode-mem
• @franlol/opencode-md-table-formatter@latest

OpenCode version

1.16.2

Steps to reproduce

1. Set HTTP_PROXY and HTTPS_PROXY to a valid local proxy, for example http://127.0.0.1:7897

2. Run:

   opencode plugin --global @franlol/opencode-md-table-formatter@latest --print-logs --log-level DEBUG

   or:

   opencode plugin --global opencode-mem --print-logs --log-level DEBUG

3. Observe that install can stall for a long time at Installing plugin package

4. Unset only HTTP_PROXY / HTTPS_PROXY and rerun the same command

5. Observe that the install succeeds quickly

Additional notes:

• curl to the same upstream works
• the local proxy is reachable and traffic is being sent to it
• the issue reproduces specifically when the explicit proxy env vars are present
• the repo currently contains a patch drift:
  • package.json patch target: @npmcli/[email protected]
  • bun.lock resolved version: @npmcli/[email protected]
