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")

@L_kevin

match role_kind:

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

[Goyo]

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.

[L_kevin]

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

[Goyo]

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.
