Unable to connect to Robot binary decode error: mpack_error_type

[milligansarah]

Upon using the setValue() method on an instance of NetworkTablesTopic<number>, the robot and Typescript app momentarily disconnect, output the above error message, then reconnect. The published value is never received by the robot program. I and a few other folks on my robotics team believe that the issue stems from an incompatibility between the ntcore-ts-client library and the recently released 2025 WPILib. Would it be possible to investigate this issue further?

Please let me know if any more details are needed to assist in diagnosing the issue and implementing a fix.

I can reproduce, let me try to debug

@milligansarah Thanks for the report. I was able to narrow it down to a few issues. Unfortunately a couple are regressions in WPILib, but I will implement workarounds to fix this.

Hi @milligansarah please try installing 3.1.2 and reopen if this is still an issue, thanks!
