DAG creation via REST API always overwritten with echo hello

[Sedymariama]

I am trying to create a new DAG with an SSH step using the REST API.
However, every time I send the request, the created dag file is overwritten with « echo hello » command instead of my step.
I did :
curl -X POST "https://dagu.sdom.com/api/v2/dags"
-H "Content-Type: application/json"
-d '{
"name": "test-ssh5",
"steps": [
{
"name": "start the script",
"executor": {
"type": "ssh",
"config": {
"user": "myuser",
"ip": "1.2.3.4",
"port": 5678,
"key": "/mysshkey"
}
},
"command": "/bin/bash /home/myuser/.....sh"
}
]
}' -u dagu:'xxxxxxxxxxxxxxxxxxxxxxxxx'

Result
The DAG is created, but its content is replaced with:
steps:

• command: echo hello
  Environment:
  • Dagu Version: 1.22.4-be57f3d(running in Docker)
  • API endpoint: /api/v2/dags
  • Authentication: basic auth

Hi @Sedymariama,
Can you try with YAML data in body instead of JSON? Currently this API accepts YAML definition only and not JSON format. For more details, you can visit https://docs.dagu.cloud/reference/api#create-dag

Thanks for your reply. I tried again with YAML as suggested, but I still get the same result.
Here is the command I used:

curl -X POST "https://dagu.sdom.com/api/v2/dags" -H "Content-Type: application/json" -u dagu:'xxxxxxxxxxxxxxxxxxxxxxxxx' -d '{ "name": "test-ssh7", "spec": "steps:\n - name: start the script\n executor:\n type: ssh\n config:\n user: myuser\n ip: 1.2.3.4\n port: 5678\n key: /mysshkey\n command: /bin/bash /home/myuser/.....sh" }'

Result : The DAG is created, but the file content is still replaced with `steps:

• command: echo hello`

@Sedymariama Can you try with the following curl command?

curl -X POST "http://localhost:8080/api/v2/dags" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "test-dag-api",
    "spec": "steps:\n  - command: echo create DAG via API"
  }'

I tested again with the exact command you suggested:

curl -X POST "https://dagu,sdom.com/api/v2/dags" -H "Content-Type: application/json" -d '{ "name": "test-dag-api", "spec": "steps:\n - command: echo create DAG via API" }' -u dagu:'XXXXXXXXXXXX'

The DAG is created, but its content is still replaced with the same command echo hello

@Sedymariama Ah, sorry about the confusion. The spec parameter isn’t live yet, but it’s coming in version 1.23 (see the changelog here: https://docs.dagu.cloud/reference/changelog#new-features).
Until then, you’ll need to make two separate requests: create the DAG first, then update the spec.

[Sedymariama]

@yottahmd Thanks for the clarification! I’ll create the DAG first, then update the spec in a separate request.

[Sedymariama]

@yottahmd Thanks ! It worked!
I created the DAG first with POST /api/v2/dags, and then updated it using PUT /api/v2/dags/{name}/spec

@Sedymariama Glad that it worked! Thanks for letting me know.
