从 Python 函数运行 Robot 框架关键字时出错 - RobotNotRunningError('无法访问执行上下文')

Question

我正在尝试从作为 flask 应用程序公开的 Python 函数运行 Robot Framework 关键字。我能够从另一个机器人测试套件调用这个 python 函数，但是当从 Flask 应用程序运行相同的函数时 - 我收到错误，RobotNotRunningError（'无法访问执行上下文'）。请有人指导如何解决这个问题。

机器人框架版本 5.0.1， Python3.9

Python脚本：

from flask import Flask, request
from robot.libraries.BuiltIn import BuiltIn
from robot.api.deco import keyword

app = Flask(__name__)
...
@app.get('/getAcctData') 
def get_acctData():
    ROBOT_LISTENER_API_VERSION = 3
    ROBOT_LIBRARY_SCOPE = 'TEST SUITE'
    endPoint=  request.args.get('myKeyword') or 'get_defaultAcct'
    username = request.args.get('userid') or 'TEST_USER'
    password = request.args.get('password') or 'TEST_PW'
    BuiltIn().import_resource('/Users/S123/myProject/Tests/keywordsLibrary.robot')
    return(BuiltIn().run_keyword('endPoint',username, password)) 

关键字库文件看起来像这样
