Mule 4, get uri params with Anypoint application

I'm new in Mulesoft, I'm following Quickstart guide. In Step 2 (https://developer.mulesoft.com/guides/quick-start/developing-your-first-mule-application), I need to receive variables from URI in this way:

[{'id' : attributes.uriParams.productId}]

But when I try my GET I have the following error in console:

**Message : "Cannot coerce Array ([{id: "2" as String {class: "java.lang.String"}}]) to Object 1| [{'id' : attributes.uriParams.productId}] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Trace: at main (line: 1, column: 1)" evaluating expression: "[{'id' : attributes.uriParams.productId}]". Error type : MULE:EXPRESSION Element : get:\products(productId):test_daniel-config/processors/1 @ test6_db_connection:test_daniel.xml:133 (Select) Element XML : SELECT product.,CONCAT('["', (GROUP_CONCAT(variant.picture SEPARATOR '","')),'"]') AS pictures,CONCAT('[', GROUP_CONCAT('{"',variant.identifierType, '":"', variant.identifier, '"}'),']') AS identifiersFROM product INNER JOIN variant ON product.uuid = variant.productUUIDWHERE product.uuid = :id; #[[{'id' : attributes.uriParams.productId}]] *

Any Ideas? Thanks!

cannot coerce Array to object error pop's up when you are using an array where you were supposed to use an object.

in the exception above the uri-param should be treated as ab object i.e. enclosed in {} but its being treated as an array of objects [{}].

this is causing the error.
