Issue with Custom Plugin: “Argument List Too Long” When Passing Large Config Parameter

SaudBinsaleh

Hello Dataiku Community,

I’m developing a custom plugin in Dataiku, and I’m facing an issue when passing a large config parameter. The parameter is a list with around 500 items, and I can see that:

•The list appears correctly in the plugin’s UI.

•It also logs correctly in the browser console using JavaScript.

•However, when I run the plugin, it fails immediately with the error:

Exception: argument list too long

My Questions

1.What is causing this issue?

2.Is there a size limit for configuration parameters in Dataiku plugins?

3.What are the best practices to handle large configuration inputs in a Dataiku plugin to avoid this error?

I appreciate any insights or workarounds! Thanks in advance.
