Azure devops Azure DevOps、AppCenter分发无法用于iOS本机ap

我正在尝试将IPA发布到App Center，我的构建定义的YAML如下所示：

# Xcode
# Build, test, and archive an Xcode workspace on macOS.
# Add steps that install certificates, test, sign, and distribute an app, save build artifacts, and more:
# https://docs.microsoft.com/azure/devops/pipelines/languages/xcode

Xcode构建任务似乎运行良好：

根据-exportPath参数，生成的IPA文件应位于/Users/vsts/agent/2.146.0/work/1/a/PPD中

但是！AppCenterDistribute步骤失败：

##[section]Starting: AppCenterDistribute
==============================================================================
Task         : App Center Distribute

==============================================================================
##[error]Error: Cannot find any file based on /Users/vsts/agent/2.146.0/work/1/a/**/*.ipa.
##[section]Finishing: AppCenterDistribute

所以问题是：我的.ipa位于哪里？为什么在exportPath中找不到我的.ipa

编辑：

我更改了exportPath参数以指定完整路径：Users/vsts/agent/2.146.0/work/1/a/PPD/Aura.ipa

现在，我在AppCenter分发任务中遇到另一个错误：

这方面运气好吗？EISDIR的可能答案是：目录上的非法操作
