Later this crashes:\n\n```javascript\nallRepos = allRepos.filter(repo =\u003e repo.full_name !== undefined);\n```\n\n\n\n\n\n\n### To reproduce\n\nInside the Sourcebot container:\n\n```javascript\nimport { giteaApi } from \"gitea-js\";\nimport fetch from \"cross-fetch\";\n\nconst api = giteaApi(\"http://gitea:3001\", {\n  token: process.env.GITEA_TOKEN,\n  customFetch: fetch,\n});\n\nconst response = await api.repos.repoGet(\"Org\", \"Repo\");\n\nconsole.log(JSON.stringify(response, null, 2));\n```\n\n```json\n\n{\n  \"size\": 0,\n  \"timeout\": 0,\n  \"data\": null,\n  \"error\": {\n    \"message\": \"Invalid response body while trying to fetch http://gitea:3001/api/v1/repos/Fairparken/Fairparken.Worker: Premature close\",\n    \"type\": \"system\",\n    \"errno\": \"ERR_STREAM_PREMATURE_CLOSE\",\n    \"code\": \"ERR_STREAM_PREMATURE_CLOSE\"\n  }\n}\n```\n\n### Sourcebot deployment information\n\nSourcebot version (e.g. v3.0.1): V5.0.4\nGittea image version: docker.gitea.com/gitea:1.26.1-rootless\n\n\n### Additional information\n\nTemporary workaround tested:\n\nI patched /app/packages/backend/dist/gitea.js inside the running Sourcebot container to use a custom fetch:\n\n```javascript\nconst customFetch = (url, options = {}) =\u003e {\n    const headers = {\n        ...(options.headers ?? {}),\n        'Accept-Encoding': 'identity',\n        'Connection': 'close',\n    };\n\n    return fetch(url, {\n        ...options,\n        headers,\n    });\n};\n\nconst api = giteaApi(config.url ?? 'https://gitea.com', {\n    token: token,\n    customFetch,\n});\n```\n\nI also added a null guard:\n```javascript\n\nallRepos = allRepos.filter((repo, index) =\u003e {\n    if (repo === null || repo === undefined) {\n        logger.warn(`Skipping null/undefined Gitea repo at index ${index}`);\n        return false;\n    }\n    return repo.full_name !== undefined;\n});\n```\n\n# Relevant code locations\n/app/packages/backend/dist/gitea.js:42\n/app/packages/backend/dist/gitea.js:161-166\n/app/packages/backend/dist/repoCompileUtils\n\n\n\n","author":{"url":"https://github.com/HueskenNiels-hue","@type":"Person","name":"HueskenNiels-hue"},"datePublished":"2026-06-30T09:31:24.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/1404/sourcebot/issues/1404"}
