need help setting up ollama #4862

OpenCode Version: 1.0.119
Operating System: Linux

Problem Description:
OpenCode fails to initialize the Ollama provider when attempting to run a command, resulting in a ProviderInitError with a TypeError: fn2 is not a function. The Ollama server is running, models are
available, and OpenCode correctly lists the Ollama models when opencode models is executed.

Steps to Reproduce:

1. Ensure Ollama is installed and running (ollama serve).
2. Pull the desired Ollama model, e.g., llama3.1:8b (ollama pull llama3.1:8b).
3. Ensure the OpenCode configuration file exists at /home/liam/.config/opencode/opencode.json with the following content:

1 {"$schema":"https://opencode.ai/config.json","provider":{"ollama":{"options":{"baseURL":"http://localhost:11434/v1"},"models":{"llama3.1:8b":{},"qwen2.5-coder:14b":{},"mistral:7b":{},
"deepseek-coder-v2:16b-lite-instruct-q5_K_M":{}}}},"model":"ollama/llama3.1:8b","mcp":{"MCP_DOCKER":{"type":"local","command":["docker","mcp","gateway","run"],"enabled":true}}}
4. Verify that OpenCode recognizes Ollama models by running: /home/liam/.opencode/bin/opencode models
(Expected: Ollama models are listed).
5. Attempt to run OpenCode with an Ollama model: /home/liam/.opencode/bin/opencode run "test message" --print-logs

Expected Behavior:
OpenCode should successfully use the configured Ollama model to generate a response.

Actual Behavior:
The command fails with the following error:

1 INFO  2025-11-28T10:57:00 +0ms service=provider providerID=ollama modelID=llama3.1:8b getModel
