ResourceNotFoundException

ResourceNotFoundException

Error message

Export {exportArn} not found.

What it means

Thrown by Floci's BCM Data Exports emulator from ListExecutions when the supplied ExportArn does not exist in the export store. The service requires a non-empty ARN and an existing export before scanning its execution records; missing exports yield ResourceNotFoundException. Note the emulator returns HTTP 400 here whereas real AWS uses 404 for this error code.

Solutions

  1. Confirm the export exists via GetExport/ListExports and use its exact exportArn.
  2. If the export was deleted, stop polling; executions are removed with the export.
  3. Capture and persist the exportArn returned by CreateExport instead of constructing ARNs manually.
  4. Recreate the export if the workflow requires execution history.

Example fix

// before
bcm.listExecutions(r -> r.exportArn("arn:aws:bcm-data-exports:us-east-1:123456789012:export/guess"));

// after
String arn = bcm.createExport(r -> r.name("cost").dataQuery(dq).refreshCadence(rc)).exportArn();
bcm.listExecutions(r -> r.exportArn(arn));
Defensive patterns

Strategy: validation

Validate before calling

Optional<String> arn = bcm.listExports().exports().stream()
    .map(ExportSummary::exportArn)
    .filter(a -> a.equals(candidateArn)).findFirst();
if (arn.isEmpty()) { /* do not poll executions */ }

Try / catch

try {
    bcm.listExecutions(r -> r.exportArn(arn));
} catch (software.amazon.awssdk.services.bcmdataexports.model.ResourceNotFoundException e) {
    // export gone: stop the polling loop
}

Prevention

When it happens

Trigger: bcmDataExportsClient.listExecutions(r -> r.exportArn(arn)) with an ARN of a deleted or never-created export, or an ARN with a wrong export name segment.

Common situations: Polling executions of an export that failed to create earlier in the workflow; using an ARN from a previous emulator session after storage reset; deleting the export then continuing to poll; malformed ARN built by hand.
