This section contains help for common errors encountered when using the CLI.
Faulty OAuth Server Address
In the CLI configuration file, the server address is set to thethings.example.com by default. If you do not change this server address to the address of your own deployment, using ttn-lw-cli login command will redirect to https://thethings.example.com/oauth/authorize?client_id=cli&redirect_uri=local-callback&response_type=code in your web browser, where the CLI needs to be authorized for exchanging an access token.
Since your server address is most likely different than thethings.example.com, you will see an error about that URL not being found in your browser, the access token will not be obtained and you will not be able to execute any further CLI commands. In your terminal, you will see something like:
INFO Opening your browser on https://thethings.example.com/oauth/authorize?client_id=cli&redirect_uri=local-callback&response_type=code
INFO After logging in and authorizing the CLI, we'll get an access token for future commands.
INFO Waiting for your authorization...
The solution to this issue would be to replace thethings.example.com occurrences with the server address of your The Things Stack deployment.
You will experience the same issue if you are using an https port other than 443 and you have not specified that port in the oauth-server-address parameter in the CLI configuration file or with --oauth-server-address flag when running the CLI. For example, if you are running The Things Stack on localhost, you need to specify the OAuth server address as 'https://localhost:8885/oauth'.
Certificate Signed by Unknown Authority
If the CA file path is not specified in the CLI configuration file (or with --ca flag when running the CLI), or if you are using self-signed certificates, using ttn-lw-cli login might result in the following error:
ERROR Could not exchange OAuth access token error=Post "https://thethings.example.com:8885/oauth/token": x509: certificate signed by unknown authority
If the CA file is present on your system, the CLI configuration file should contain ca: /path/to/ca.pem or you should run the CLI with --ca="/path/to/ca.pem" flag, and you should also import the CA file using your web browser’s certificate manager to make sure it’s trusted by your system.
You can also run the CLI with the --fetch-ca flag which will make sure to connect to the server, fetch the CA file and configure the path to it in your CLI configuration file.
No Collaborator Set
Many CLI commands require that a user or organization is set to grant permissions over an entity. For example, to create an application:
$ ttn-lw-cli applications create app1 --user-id user1
Permission Denied
If a user (specified with the --user-id flag) does not have sufficient rights to perform the desired action, you will face an error such as:
error:pkg/auth/rights:insufficient_application_rights (insufficient rights for application `app1`)
See Users and Organizations section for more info on rights management.
Invalid Identifiers
When creating an entity using the CLI, if the ID value that you use does not follow The Things Stack naming convention, you will face an error. For example, using ttn-lw-cli gateways create My_Gateway command would result in the following error:
error:pkg/errors:validation (invalid `gateway_id`: value does not match regex pattern "^[a-z0-9](?:[-]?[a-z0-9]){2,}$")
field=gateway_id
name=GatewayIdentifiersValidationError
reason=value does not match regex pattern "^[a-z0-9](?:[-]?[a-z0-9]){2,}$"
