Request had invalid authentication credentials. Expected OAuth 2 access token error in cloud speech api

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

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
