ProviderInitError with Anthropic

Issue

Whenever I try to use Claude with my own API Key, I get the following error. I am not sure why.

+1 for Deepseek, and nothing useful in logs:

ERROR 2025-08-06T14:05:21 +4ms service=tui failed to send message: POST "http://127.0.0.1:45983/session/ses_7804c9534ffep6oEz0sfzrT8eF/message": 400 Bad Request {"name":"ProviderInitError","data":{"providerID":"deepseek"}}

can you show me what's in ~/.cache/opencode

can you show me what's in ~/.cache/opencode

ls ~/.cache/opencode
models.json package.json tui version

 opencode % ls
 models.json   package.json   tui  󰡯 version

also having this issue, failing on 0.4.2 and 0.3.112

mine is working as of 0.4.12

I face the same issue since upgrading from opencode 0.3.133 to opencode 0.4.26 with GitHub Copilot as backend.

Things I tried so far without success:

opencode auth logout followed by opencode auth login
rm -rf ~/.cache/opencode

I am not sure what is the problem here. I haven't been able to use open code because of it :(

1+ from copilot, 0.4.45 version

ERROR 2025-08-14T11:48:58 +9ms service=default providerID=github-copilot name=ProviderInitError message=ProviderInitError cause=ResolveMessage: Cannot find module '/home/taeho/.cache/opencode/node_modules/@ai-sdk/openai-compatible' from '/$bunfs/root/opencode' fatal

@maxarndt

@maxarndt @ksm0709 I was getting same error with copilot - for me it was a corporate firewall issue. Looks like recent opencode update requires bun package upgrades from openai and zod that were being blocked. So I had to install these then, then logout of copilot and log back in, now working fine
