If you have a tool call with no input (or all input is forced+hidden), you get an error back from the AWS API that toolConfig.tools[0].inputSchema.json is invalid.
Currently that ends up as null as docroot/modules/contrib/ai_provider_aws_bedrock/src/Plugin/AiProvider/BedrockProvider.php:396 is run with no $parameters.
Call an agent with a function call with no exposed parameters.
Explored:
inputSchema: AWS error due to missing required propertyinputSchema.json.properties an empty array: AWS error due to array when expecting objectinputSchema.json.properties an empty object: AWS SDK error due to expecting an array :P{"type":"object"} in \Drupal\ai\OperationType\Chat\Tools\ToolsFunctionInput::renderFunctionArray: OpenAI error due to peroprties being required.So propose this is handled as a special case where we do 4, but in the AWS Bedrock provider (we already have custom code there anyway).
Implement the fix.
