Please include the code. – Conducive

THis is indeed not a valid URI; somewhere in your config files or wherever you put 192.168.2.7:3000 and that's not a valid URI; you probably meant http://192.168.2.7:3000 – Nirvana

Answer 1

you should remove space from url and define scheme http or https

Thank you so mcuh. Your answer working to me – Sierrasiesser

Answer 2

Do not put " while defining the URL in the properties file like this:

dev.baseURL=http://localhost:8080/products/

Answer 3

If you are Using localhost then pass url like this- http://localhost:8080/api/notes defining scheme is important (http/https) do not use space also.

Answer 4

Make sure you do not forget the // in http://

@AdityaPatnaik well, the accepted answer doesn't contain the // characters exactly. Still a comment to that answer would have been sufficient – Townsend

This does not provide an answer to the question. Once you have sufficient reputation you will be able to comment on any post; instead, provide answers that don't require clarification from the asker. - From Review – Townsend

@cyberbrain, thanks for your review. I feel the reason why the accepted answer doesn't have it or implicitly has it is because it was already covered in a comment on the question back in 2015. Also, using a // after http is a basic understanding and doesn't require an explicit mention in the answer. I assume that the user whose answer is accepted thought this fundament to be understood by the readers. – Jellicoe

Answer 5

Make sure you don't have spell mistake in URL,http:// or https://

Answer 6

While we are using any services which are running on our local machines, please try to call the service by using the http protocal instead of directly calling the service. Example: localhost:1234/hello(wrong will give the above exception) http://localhost:1234/hello(correct way)
