Hi @ronttizz
Find similar issue #16946.
Issue title A stacktrace with a disorienting message is shown for az apim api import
Create time 2021-02-16
Comment number 3

Possible solution:
The error message "can only concatenate str (not "NoneType") to str" is shown in both issues. In the existing issue, the error message is caused by not specifying the --specification-format parameter. Similarly, in the new issue, the error message is caused by a similar issue. The solution to the new issue is to specify the --specification-format parameter. You can check all the valid values for the --specification-format parameter by running "az apim api import -h".

Please confirm if this resolves your issue.

az config set core.login_experience_v2=off
Could help to resolve errors, until it's fixed.

Confirmed that @v-starodubov's suggestion allows me to successfully login. Would be nice if this was fixed ASAP though since it's a serious regression.

Same issue for our on-premises or hybrid environment. After the work-around for this different issue (#28997):

az account clear
az config set core.enable_broker_on_windows=false

I get the error in this GitHub issue above. However, I still end up being logged into the account. It just throws the error.

According to the log provided by @m1iktea in #29241 (comment), https://management.azure.com/tenants?api-version=2022-12-01 API returned

cli.azure.cli.core.sdk.policies: {"value":[{"id":"/tenants/122f6959-7492-42d8-8cf5-f9233ac18c4f","tenantId":"122f6959-7492-42d8-8cf5-f9233ac18c4f","tenantCategory":"Home"}]}

displayName property is missing from the response JSON. This contradicts the ARM public document https://learn.microsoft.com/en-us/rest/api/resources/tenants/list?view=rest-resources-2022-12-01

@ronttizz, @v-starodubov, @XhmikosR, @TheOnlyWei, could you also check the --debug log and share the HTTP trace of https://management.azure.com/tenants?api-version=2022-12-01 API call?

It seems that this error is not blocking me from the login itself like @TheOnlyWei pointed out.

As I expected, the responses of all these https://management.azure.com/tenants?api-version=2022-12-01 REST calls lack displayName. I have created #29245 to handle it, but I will also report it to ARM team.

Before #29245 is merged and released, you may disable the subscription selector by running

az config set core.login_experience_v2=off

See https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli-interactively#subscription-selector

I am using the latest CLI.

>az --version
azure-cli                         2.65.0

In my case, the account used is an External Identity to the directory, and indeed I am not able to retrieve the tenant's Name even on Azure Portal with the account.

Here is the view of the same tenant from the tenant's owner.
