Getting parser error

[karkir0003]

Hi,
I hope you are doing well. I have a flask app that I'm trying to add in flasgger to in order to take advantage of Open API. Here is a sample of my code

from flasgger import Swagger
from flasgger.utils import swag_from
# and other code imports here

app = Flask(
    __name__,
    static_folder=os.path.join(os.getcwd(), "frontend", "playground-frontend", "build"),
)

CORS(app)
app.config['SWAGGER'] = {
    'title': 'DLP API',
    'uiversion': 3,
    'host': 'localhost:8000',
    'basePath': '/'
}
swagger = Swagger(app, template_file="dlpapi.yaml")

@app.route("/test")
@swag_from('dlpapi.yaml')
def verify_backend_alive():
    return {"Status": "Backend is alive"}

Here is the yaml file I'm trying to get rendered

openapi: '3.0.0'
info:
  title: DLP API 
  description: API endpoints for the Deep Learning Playground Project
  version: '1.0.0'
paths:
  /test:
    get:
      summary: A simple endpoint to test if our backend is alive
      responses:
        200: 
          description: Test Backend alive
          content:
            application/json:
              schema:
                type: object
                properties:
                  Status:
                    type: string 
                    example: "Backend is alive"

Problem:
When I spin up localhost:8000/apidocs, I get this error

Investigation Strategies I've Tried:

• Went into https://codebeautify.org/yaml-validator and pasted the above yaml in to see if there is any syntax error. There isn't a syntax error according to the tool
• I also make sure to add openapi version properly along with info and paths
• I also tried adding in the template_file="dlpapi.yaml in the Swagger constructor in Flask. That didn't really do anything

Anything else you'd suggest I try to resolve this issue

Another error that came up when I typed in localhost:8000/apidocs

@rochacbruno could you or someone from the flasgger team please help me out

UPDATE: resolved this issue. I needed to set app.config["SWAGGER"]["openapi"] to version 3.0.2 according to the README with uiversion: 3
