AWS reranker model: Model Error, Error while deserializing header: HeaderTooLarge : 400

2024-09-30T09:41:15,449 [INFO ] W-model-3-stdout com.amazonaws.ml.mms.wlm.WorkerLifeCycle - mms.service.PredictionException: Error while deserializing header: HeaderTooLarge : 400

I got an error when trying to activate this line of code:

response = predictor.predict({
"query": query,
"documents" : documents,
"topk" : topk
})

No repository file or test is identified. Start by reproducing the failure at the predictor.predict entry point with the shown query, documents, and topk inputs, then inspect the resulting model-service error. Done means identifying the cause of the HeaderTooLarge deserialization failure and documenting a verified working request or a focused fix location.
