Fail to deploy Azure Playwright Workspace via bicep

This is the bicep I am using now, in the module where declare my playwright workspace resource:

import { ResourceName, formatRestrictedName } from '../../resource-name/ResourceName.bicep'
@description('Name properties for the Playwright workspace.')
param name ResourceName
@description('Location for the Playwright workspace. Only override if you have a good reason to do so.')
param location string = resourceGroup().location
var workspaceName = formatRestrictedName({
  resourceType: 'pws'
  ...name
})
var storageAccountName = toLower(formatRestrictedName({
  resourceType: 'st'
  ...name
  feature: 'testreports'
}))
resource playwrightWorkspace 'Microsoft.LoadTestService/playwrightworkspaces@2026-02-01-preview' = {
  name: workspaceName
  location: location
  tags: resourceGroup().tags
}
resource storageAccount 'Microsoft.Storage/storageAccounts@2025-01-01' = {
  name: storageAccountName
  location: location
  tags: resourceGroup().tags
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'StorageV2'
  properties: {
    supportsHttpsTrafficOnly: true
    allowSharedKeyAccess: false
    encryption: {
      services: {
        file: { enabled: true }
        blob: { enabled: true }
      }
      keySource: 'Microsoft.Storage'
    }
    accessTier: 'Hot'
  }
}
@description('Resource ID of the Playwright workspace.')
output id string = playwrightWorkspace.id
@description('Name of the Playwright workspace.')
output name string = playwrightWorkspace.name
@description('Name of the associated storage account.')
output storageAccountName string = storageAccount.name

This module is then imported and used to set up the resource in my main.bicep. I am using this pattern with all my resources, and there are no issues.

module playwrightWorkspace './modules/resource/playwright-workspace/main.bicep' = {
  scope: resourceGroup
  name: 'playwright-workspace'
  params: {
    name: baseResourceName
    location: location
  }
}

However, I still get this error when deploying using azure pipeline:

ERROR: {"code": "InvalidTemplateDeployment", "message": "The template deployment 'deploy-20260515.7' is not valid according to the validation procedure. The tracking id is '0044d951-c894-424e-bd5a-f49bdacf7f3d'. See inner errors for details."}

Inner Errors:

{"code": "FailedToProcessTemplateDeploymentValidation", "message": "Resource provider 'MICROSOFT.LOADTESTSERVICE' failed to process validation for resource type 'LOADTESTS'."}

Inner Errors:

{"code": "NoResourceTypeEndpointAvailable", "message": "'Microsoft.LoadTestService/playwrightWorkspaces' Resource provider doesn't support api-version 2026-02-01-preview in 'westeurope'. Number of endpoints before filtering based on feature flags : 0."}

Can you also share ResourceName.bicep? It seems it is not error with the resource itself but some code in your bicep files.
