Missing components from response object for bedrock client about paws

[DyfanJones]

I think I have a possible solution.

remotes::install_github("dyfanjones/paws/paws.common", ref ="unmarshal_header")

I believe aws sdk go v1 would have this bug as it skips the unmarshalling of headers that's first character is the same when set to lower case i.e. contentType
https://github.com/aws/aws-sdk-go/blob/main/private/protocol/rest/unmarshal.go#L117-L122

However botocore doesn't do this and would unmarshal all headers 🤔 when location is found.

library(paws)
client <- bedrockruntime(config(credentials(profile = "paws")))

body <- list(prompt = "\n\nHuman: Tell me a funny joke about outer space\n\nAssistant:") |>
  jsonlite::toJSON(auto_unbox = TRUE)

response <- client$invoke_model(
  body = body,
  modelId = "ai21.j2-ultra",
)

response$contentType
#> [1] "application/json"
