fix(llms): normalize scheme and port in Ollama base URL#7132parthiban-sivakumar wants to merge 2 commits into
Conversation
OLLAMA_HOST follows Ollama's own convention and may be a bare host
("0.0.0.0") or a host:port pair ("127.0.0.1:11434") rather than a full
URL. _normalize_ollama_base_url only appended "/v1", so those values
produced invalid base URLs such as "0.0.0.0/v1", and every request
failed with the misleading error "Failed to connect to OpenAI API:
Connection error." - confusing, since no OpenAI model was requested.
Fill in the missing parts the way Ollama's own client does: prepend
http:// when no scheme is present, append the default port 11434 when
none is present and the scheme is http (https implies 443), then append
the /v1 suffix the OpenAI-compatible endpoint requires.
Six of nine realistic OLLAMA_HOST forms were affected, including
127.0.0.1:11434, which is Ollama's documented default.

Normalize only the parsed path.
Line 114 removes a trailing / from a query or fragment before parsing. For example, http://localhost:11434/v1?redirect=/ becomes http://localhost:11434/v1?redirect=. A URL such as http://localhost:11434/?q=1 also produces //v1.

Answering my own question for anyone who lands here: this was closed by the First-time contributor issue required workflow, not by a failing check. Both CI checks passed — the workflow's job is to close first-time PRs that have no linked issue, so it reports I've now followed the steps from the bot's comment:
GitHub wouldn't let me reopen this one ( Thanks @Vidit-Ostwal — no reply needed here, please review #7206 instead. Closing the loop so this doesn't sit as an unanswered question. |

Problem
OLLAMA_HOSTfollows Ollama's own convention, where a bare host or ahost:portpair is normal — Ollama's client fills in the scheme and port itself. CrewAI's_normalize_ollama_base_urlonly appended/v1, so anyOLLAMA_HOSTwithout a scheme produced an invalid base URL.With
OLLAMA_HOST=0.0.0.0set (the standard way to make the Ollama server listen on all interfaces):Every call then fails:
The message names OpenAI even though a local Ollama model was requested, because
ollama/*routes toOpenAICompatibleCompletion. That sends users debugging API keys and networking rather than a malformed URL.Affected values — 6 of 9 realistic forms, including
