Error reading directory: C:\Program Files\GrafanaLabs\Alloy\textfile_inputs

[fluidum]

What's wrong?

After installing Grafana Alloy on Windows I noticed once a minute logged errors.

When I created directory C:\Program Files\GrafanaLabs\Alloy\textfile_inputs the error dissapeared.

Steps to reproduce

cd "%TEMP%" && powershell -c Invoke-WebRequest "https://storage.googleapis.com/cloud-onboarding/alloy/scripts/install-windows.ps1" -OutFile "install-windows.ps1" && powershell -executionpolicy Bypass -File ".\install-windows.ps1" -GCLOUD_HOSTED_METRICS_URL "https://<GCLOUD_HOSTED_METRICS_URL>.grafana.net/api/prom/push" -GCLOUD_HOSTED_METRICS_ID ">GCLOUD_HOSTED_METRICS_ID>" -GCLOUD_SCRAPE_INTERVAL "60s" -GCLOUD_HOSTED_LOGS_URL "https://<GCLOUD_HOSTED_LOGS_ID>/loki/api/v1/push" -GCLOUD_HOSTED_LOGS_ID "<GCLOUD_HOSTED_LOGS_ID>" -GCLOUD_RW_API_KEY "<GCLOUD_RW_API_KEY>"
