Hi @pallakartheekreddy we are facing this error in content service deployed in Oracle cloud.

thanks @gandham-santhosh.
@pallakartheekreddy - can you check why this service isn't working on OCI?

[gandham-santhosh]

@pallakartheekreddy can you please share an update on this?

[pallakartheekreddy]

@gandham-santhosh As discussed over the call, I have tried both the URLs suggested by @ddevadat but still getting the same javax.json.stream.JsonParsingException exception.

oss url by default sends chunked response. The content service expect a single stream for json parse. If we use OSS s3 url frontended by an nginx reverse proxy, as setting is added in the nginx file

client_max_body_size 0; #setting to avoid sending response as chunked
This will avoid the response sent as chunked data.
