Bug Description

Left (Left(docId: KAqvylhRb-
snapshot: {"document":{"type":"editor","children":[{"type":"text","delta":[{"insert":"fdgfd"}]},{"type":"math_equation","attributes":{"math_equation":null}},{"type":"text","delta":[{"insert":"fdsaf"}]},{"type":"text","delta":[{"insert":"fdsaf"}]},{"type":"text","delta":[{"insert":"aa"}]},{"type":"math_equation","attributes":{"math_equation":"E"}},{"type":"text","delta":[{"insert":"dfaf"}]},{"type":"math_equation","attributes":{"math_equation":"E"}},{"type":"text"}]}}

Expected Behavior

{"type":"math_equation","attributes":{"math_equation":null}}
to be
{"type":"math_equation","attributes":{"math_equation":""}}

or no render error

Operating System

Darwin13.1（version 22C65）

AppFlowy Version(s)

1.0.0+1

Screenshots

No response

Additional Context

PS: I don't know what flutter and rust do when modifying values. Maybe write_snapshot and document_rev_table, and then pull the data out of it. But I spent a lot of time trying to figure it out.
Because of FFI, I can't debug directly, which is a little sad

Hi, @huang12zheng. Thanks for reporting.

You can debug the Rust code by executing AF-desktop: Debug Rust.

Here're the steps.

Get the process id of AppFlowy
Executing the AF-desktop: Debug Rust task.
Input the process id.
Set a breakpoint to debug the code.
