Please provide sufficient information.

It is probably a syntax error in your python file.

Code like this

match role_kind:
          case st.session_state.locale.radio_text1:
                c2.selectbox(label=st.session_state.locale.select_placeholder2, key="role",
                options=st.session_state.locale.ai_role_options)
           case st.session_state.locale.radio_text2:
                c2.text_input(label=st.session_state.locale.select_placeholder3, key="role")

You need at least Python 3.10 version to use this new syntax with match case statements.

Trying to compile your code in Python 3.11 yields:

File "test.py", line 5
    case st.session_state.locale.radio_text2:
                                             ^
IndentationError: unindent does not match any outer indentation level

as expected since the case clauses are not aligned.

yes, i use python 3.11 version native env. But streamlt seems not support this version??
And when I use if/else replace match case, it succeed

Streamlit works fine with Python 3.11, Streamlit Cloud doesn’t. The relevant syntax hasn’t changed from 3.10 to 3.11, the error message is exactly the same with both versions.
