Error message

Scoop export is in unkown or invalid format! Try updating Scoop and try again.\n\nContents:\n{result}

What it means

An InvalidDataException thrown in ScoopFactory's fallback parser when the plain-text export line equals `"apps":` or `"buckets":`. The factory first tries JSON deserialization (the modern Scoop export format since July 2022); on JsonException it falls back to line-based parsing. Encountering raw JSON keys in that fallback path means the export is a corrupted/truncated JSON blob that also fails plain-text parsing, so it is rejected with an upgrade-Scoop hint and the full contents attached.

Solutions

1. Run `scoop update` to update Scoop itself, then retry the export.
2. If it persists, run `scoop reset` or reinstall Scoop to repair its scripts.
3. Manually run `scoop export` and inspect the output for truncation or encoding issues.
4. Check the Scoop GitHub issues for the installed version's known export bugs.

// Sanity-check scoop export output before parsing.
var result = RunScoopCommand("export");
if (string.IsNullOrWhiteSpace(result)) return results;
bool looksLikeJson = result.TrimStart().StartsWith("{");
if (looksLikeJson && (!result.Contains("\"apps\"") || !result.EndsWith("}")))
    throw new InvalidDataException("Scoop export appears truncated; update Scoop and retry.");

try { /* parse scoop export */ }
catch (InvalidDataException ex) when (ex.Message.Contains("Scoop export is in unkown"))
{ /* run `scoop update`, then retry export once */ }

When it happens

Trigger: Scoop's `export` command produced output that is neither valid JSON nor valid plain text: truncated JSON (starts with `{` but cut off), a Scoop version that emits a half-broken format, or a pipe encoding issue that mangled the output.

Common situations: Outdated Scoop version with a known export bug; Scoop updated mid-way leaving mixed-format state; terminal/redirect encoding corrupted the export; Scoop bucket corruption.
