What causes "organization %s not found" in hyperledger/fabric?

Verify the exact Name field of the org in configtx.yaml and pass it verbatim to -printOrg (match is exact, not fuzzy).

organization %s not found

Error message

organization %s not found

What it means

In `doPrintOrg` (cmd/configtxgen/main.go:147), after scanning all Organizations in the loaded profile, none matched the name given via `-printOrg`. configtxgen exhausts the org list without finding a case-sensitive match and returns `organization <name> not found`.

Solutions

Verify the exact Name field of the org in configtx.yaml and pass it verbatim to -printOrg (match is exact, not fuzzy).
Ensure FABRIC_CFG_PATH points to the directory containing the intended configtx.yaml.
Do not confuse the org's MSP ID (`ID:`) with its `Name:` — -printOrg matches Name.
Run `configtxgen -printBlock` or inspect the profile to confirm the org is listed under Organizations.

Example fix

// before
$ configtxgen -profile MyProfile -printOrg PeerOrgMSP   // MSP ID, not Name -> not found
// after
$ configtxgen -profile MyProfile -printOrg PeerOrg      // matches 'Name: PeerOrg' in configtx.yaml

Defensive patterns

Strategy: validation

Validate before calling

// Verify the org name exists before calling configtxgen
import yaml
cfg = yaml.safe_load(open('configtx.yaml'))
names = [o['Name'] for o in cfg['Organizations']]
if org_name not in names:
    raise SystemExit(f"org '{org_name}' not found; available: {names}")

Try / catch

out, err := exec.Command("configtxgen", "-profile", profile, "-printOrg", orgName).CombinedOutput()
if err != nil {
	if strings.Contains(string(out), "not found") {
		return fmt.Errorf("check -printOrg name matches the 'Name:' field; FABRIC_CFG_PATH=%s; output: %s", os.Getenv("FABRIC_CFG_PATH"), out)
	}
}

Prevention

Copy the org Name exactly from configtx.yaml — matching is case-sensitive and exact.
Set FABRIC_CFG_PATH explicitly to the directory holding your configtx.yaml.
Remember -printOrg takes the org Name, not the MSP ID.
Script org lookups from the parsed YAML instead of hardcoding names.

When it happens

Trigger: Running `configtxgen -printOrg SomeOrg` where SomeOrg does not exactly (case-sensitively) match any org's Name field under Organizations in the configtx.yaml profile, or when configtx.yaml/`FABRIC_CFG_PATH` points at a config that lacks the org entirely.

Common situations: Typo in the org name passed to -printOrg; wrong FABRIC_CFG_PATH so a different (default/empty) configtx.yaml is loaded; passing the org's MSP ID instead of its Name; org present in another profile section but not in Organizations.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
