Get Error on running agent

[xyzhu68]

Hi,
after I upgrade ragflow to v0.20.1, I cannot run agents:
"module 'agent.tools' has no attribute 'AnswerParam'"

Will fix it.

Hi,
after restarting windows and restarting "docker desktop" ragflow container, I have new issues:

1. if open old agents, only blank site is shown
2. The left panel (list of components) in agent editor is missing
   Another question: there is no branch v0.20 yet? If I give "git branch", I get "HEAD detached at v0.20.1":

v0.20 is just a tag on our main branch. Could you try our newly released v0.20.3?
