Additional Context

[arekpalinski]

I think I’ve run into the same issue. I followed the following example:

https://docs.microsoft.com/en-us/azure/event-grid/custom-event-to-queue-storage#subscribe-to-a-custom-topic

so I had a script like:

storageid=$(az storage account show --name $storageAccountName --resource-group $storageResourceGroup --query id --output tsv | tr -d '\r')
queueid="$storageid/queueservices/default/queues/$queueName" 

az eventgrid event-subscription create --source-resource-id $storageid --name $eventSubscriptionName --endpoint-type storagequeue --endpoint $queueid --included-event-types Microsoft.Storage.BlobCreated

what resulted in Operation failed with status: 'Bad Request'. Details: 400 Client Error: Bad Request for url: because of %0D character in the middle of URL. I have workaround this by adding | tr -d '\r' here:

storageid=$(az storage account show --name $storageAccountName --resource-group $storageResourceGroup --query id --output tsv | tr -d '\r')

There are 2 ways to trigger this issue on WSL.

Calling az installed on Windows

If you are calling az installed on Windows system instead of the az installed on WSL Linux, you will hit this issue.

To identify which az you are calling, run

# az installed on Windows
$ which az
/mnt/c/Program Files (x86)/Microsoft SDKs/Azure/CLI2/wbin/az

# az installed on WSL Linux
$ which az
/usr/bin/az

Call az installed on Windows, save the result and let python3 help us display its raw value:

$ result=$(az account show --query id --output tsv)
$ python3 -c "import sys; print(sys.argv)" "$result"
['-c', '0b1f6471-1bf0-4dda-aec3-cb9272f09590\r']

Solution

Always stay in WSL Linux. Make sure az is installed following Install the Azure CLI on Linux and /mnt/c/Program Files (x86)/Microsoft SDKs/Azure/CLI2/wbin/az is not called.

Now it works correctly:

$ result=$(az account show --query id --output tsv)
$ python3 -c "import sys; print(sys.argv)" "$result"
['-c', '6b085460-5f21-477e-ba44-1035046e9101']

Executing .sh script with CRLF

As @zhoxing-ms stated in https://github.com/Azure/azure-cli/issues/13573#issuecomment-650686531, say we have test.sh with CRLF as End of Line Sequence:

result="somevalue"
python3 -c "import sys; print(sys.argv)" "$result"

When executing the script in WSL:

$ . test.sh
['-c', 'somevalue\r\r']

Solution

To fix it, you may open the script with VS Code:

code test.sh

Select End of Line Sequence and change it to LF:

Now it works correctly:

$ . test.sh
['-c', 'somevalue']
