Error message

ScheduledTaskJob failed: No valid container was found. Is the container name correct?

What it means

ScheduledTaskJob collects the resource's running containers (applications via getCurrentApplicationContainerStatus, services via running applications+databases), then executes only in a container whose name starts with '{task->container}-{resource->uuid}'. If the loop completes without a match — multiple containers and a non-matching stored name — it throws NonReportableException so the ScheduledTaskExecution row is marked failed and the scheduled-errors channel is notified without flagging an app bug.

Solutions

Edit the scheduled task and set 'Container' to the bare service name shown on the resource's container list (the part before '-uuid').
Verify with docker ps on the server that the container is running — stopped containers are excluded from the candidate list.
If the resource now has exactly one container, clear the container field so the single-container shortcut applies.

Example fix

// before: full container name stored — never prefix-matches
$task->container = 'myapp-' . $resource->uuid;
$task->save();

// after: bare service name; the job appends '-{resource->uuid}' itself
$task->container = 'myapp';
$task->save();

Defensive patterns

Strategy: validation

Validate before calling

// Before dispatching ScheduledTaskJob, verify the target exists
$containers = $resource->type() === 'application'
    ? getCurrentApplicationContainerStatus($server, $resource->id, 0)->pluck('Names')
    : $resource->applications()->get()
        ->concat($resource->databases()->get())
        ->filter(fn ($c) => str(data_get($c, 'status'))->contains('running'))
        ->map(fn ($c) => data_get($c, 'name') . '-' . $resource->uuid);
$prefix = ($task->container ?? '') . '-' . $resource->uuid;
$valid = $containers->count() === 1 || $containers->contains(fn ($n) => str_starts_with($n, $prefix));
if (! $valid) { /* flag task as misconfigured before it ever runs */ }

Try / catch

catch (NonReportableException $e) { record on the ScheduledTaskExecution log and notify the task owner with the container list — this is a config error, retrying identical input cannot succeed. }

Prevention

Store bare service names in task->container; never the full '-uuid' container name.
When renaming compose services, update scheduled tasks in the same change.
Periodically reconcile task container fields against actually running containers.

When it happens

Trigger: Scheduled task on a multi-container application or service where task->container does not prefix-match any running container name; the compose service was renamed after the task was created; only a subset of containers running so the named one is missing from the list.

Common situations: Renaming a service in docker-compose and forgetting the scheduled task; task created against one container, later more services added; entering the full container name (with -uuid) into the task's container field, which can never prefix-match.
