A 400 response usually indicates a validation failure or missing required parameters, but can trigger for many reasons. This sample 400 error represents an attempt to view a storage group that doesn't exist:
{
type: 'validation-error',
title: 'Validation failure',
instance: '9378a1a8-bead-4ceb-931c-a8c0004cb1e2',
status: 400,
detail: 'Validation failed. Please review the errors.',
errors: [
{
type: 'error-types/invalid-value',
title: 'Invalid value',
detail: 'Unable to find the given storage group.',
field: 'storageGroupId'
}
]
}
