ansible uri module fails (lineno\\": 0\\n}' is not of type u'object) (Input payload validation failed)

Question

ansible 2.7, same call over curl works fine>

curl -X POST " -H "accept: application/json" -H "Content-Type: application/json" -d "{ \"hostname\": \"string\", \"name\": \"string\", \"service\": \"string\", \"extra\": {}, \"args\": [ \"string\" ], \"module\": \"string\", \"filename\": \"string\", \"pathname\": \"string\", \"requestid\": \"string\", \"message\": \"string\", \"funcname\": \"string\", \"levelname\": \"INFO\", \"lineno\": 0}"

uri module gives me the following error:

foremost: why don't you heed its advice and stop using deprecated syntax for the headers? secondarily, as a "stop making my eyes bleed," you should use single-quotes for your curl body since the entire payload is literal: -d '{"hostname": "string", etc etc}' — mdaniel
Also, had you not truncated your error message, we might be able to help you further, but here we are — mdaniel

"json": {"errors": {"": "u'{\n \"hostname\": \"string\",\n

I'm pretty sure you are getting bitten by the json-to-object-to-string mental bug; since you already have JSON text, the ideal outcome would not be to parse it into an object and then have ansible serialize it back into a string, lest you run the very real risk of exactly what happened here: calling str(body) where body was a dict

Just remove the | to_json from your body: {{ }} expression and I would expect it will end better than what you are currently experiencing
