Mistral provider fails: auto-install ENOENT + ZodError on streaming responses (Homebrew install) #5997
Closed as duplicate
Description
Environment
- opencode version: 1.0.184 (Homebrew on macOS ARM64)
- Model:
devstral-2(Mistral provider)
Issue 1: Auto-install of @ai-sdk/mistral fails (ENOENT)
When selecting a Mistral model, opencode tries to auto-install @ai-sdk/mistral but fails with:
ENOENT: no such file or directory, posix_spawn '/opt/homebrew/Cellar/opencode/1.0.128/libexec/lib/node_modules/opencode-ai/node_modules/opencode-darwin-arm64/bin/opencode'
The binary path opencode-darwin-arm64/bin/opencode doesn't exist in the Homebrew installation layout.
Workaround: Manually install the SDK:
cd /opt/homebrew/Cellar/opencode/1.0.184/libexec && npm install @ai-sdk/mistralIssue 2: ZodError after SDK is installed
Even after manually installing @ai-sdk/mistral, using the Mistral model produces ZodError validation failures:
ZodError: [
{
"expected": "string",
"code": "invalid_type",
"path": ["finish"],
"message": "Invalid input: expected string, received object"
},
{
"expected": "object",
"code": "invalid_type",
"path": ["part"],
"message": "Invalid input: expected object, received undefined"
},
{
"expected": "string",
"code": "invalid_type",
"path": ["delta"],
"message": "Invalid input: expected string, received undefined"
}
...
]
This suggests @ai-sdk/mistral is not correctly parsing Mistral's streaming response format.
Screenshots
Expected Behavior
- Auto-install should work on Homebrew installs
- Mistral provider should correctly handle streaming responses
