The matrix-angular-sdk web app reports the following error:

On jSynapse console there are no errors

You need to send JSON like this:

{
"type": "m.login.recaptcha",
"challenge": "challenge token",
"response": "user-entered text"
}

Here is a client/server example on how to perform recaptcha auth:
https://code.google.com/p/recaptcha/wiki/HowToSetUpRecaptcha

Also, I am currently reviewing the recaptcha authentication implementation and we might need to fix the private key handling server-side. Meanwhile please check password authentication if you can.

Thanks

That's correct, what you have to do is to apply for recaptcha key here: https://www.google.com/recaptcha/intro/index.html and to put a file named jsynapse.properties containing a key as recaptcha.private.key=KEY_VALUE, e.g.

recaptcha.private.key=6Ldbaxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Sounds a little bit complicated, we plan to expose all these in an admin UI where you could just upload the private key.

Thanks. It works now. i wonder how to make it working locally without recaptcha while developing.

You could use the password schema, that is register by posting type of "type": "m.login.password" instead recaptcha, e.g.

{
"type": "m.login.password",
"user": "obo",
"password": "dodo"
}
