Question

i have followed the google cloud speech api quickstart of requesting api by using

curl -s -H \"Content-Type: application/json\" \\
     -H \"Authorization: B         


        

Answer 1

Replace $(gcloud auth application-default print-access-token) with what gets printed when you call the command.

Answer 2

I fixed the problem by logging out, and logging in to agree to some new terms and conditions google have made since last time I used google clouds (firebase in my case).

Answer 3

It could be that The Application Default Credentials are not available

Try to login by running

gcloud auth application-default login

And follow the instructions, reference: gcloud auth application-default login

If you want to make sure the authentication process went well, run:

gcloud auth application-default print-access-token

You should see an access token, reference gcloud auth application-default print-access-token

Answer 4

Samir's solution worked for me.

Just a reminder that if using other software interacting with GCP, you may have to restart software before the auth takes effect.

In my case, when using RStudio, I ran gcloud auth application-default login to authenticate, then command + shift + f10 to restart the R session, and then everything was good to go
