>            Reporter: Zhimin Wu

> h3. Root Cause
> The root cause of the issue is that the size of the list passed from the frontend exceeds the maximum limit allowed for form-urlencoded requests in Spring. The default limit for the growth of arrays and collections in Spring's DataBinder class is set to 256:
> {code:java}
> public static final int DEFAULT_AUTO_GROW_COLLECTION_LIMIT = 256;{code}
> To address this issue, you may need to adjust the configuration related to the form-urlencoded request handling in Spring to accommodate larger list sizes being passed from the frontend. This could involve increasing the maximum limit for auto-growing collections or implementing alternative solutions to handle larger input data efficiently.
> If you need further assistance or guidance on how to modify the configuration to resolve this issue, please let me know.
