Google App Engine "Error parsing ./app.yaml: Unknown url handler type"

In case anyone else comes across this, I had the same issue. You must add TWO spaces for all subdirectories. Make sure the words are in line with "url".

Doesn't work:

- url: /
script: phpMyAdmin/index.php
secure: always
login: admin

Doesn't work:

- url: /
 script: phpMyAdmin/index.php
 secure: always
 login: admin

WORKS:

- url: /
  script: phpMyAdmin/index.php
  secure: always
  login: admin

Also, change the line to update the app from this:

appcfg.py -R -A my_application_id -V phpmyadmin update .

To this:

appcfg.py --oauth2 -R -A my_application_id -V phpmyadmin update .

For some odd reason, the first command asks for your email and password (my personal email didn't work). Using the second command with the --oauth2 option just works.

In my case, it was not a whitespace issue.

I originally had the app.yaml file:

runtime: nodejs12

handlers:
- url: /.*
  secure: always

... more handlers here ...

which produced the error when deploying

Unknown url handler type.
<URLMap 
    secure=always
    ...
    >

The docs at https://cloud.google.com/appengine/docs/standard/nodejs/config/appref#handlers_element indicated that I was missing script: auto in my handler element.

In order to use static handlers, at least one of your handlers must contain the line script: auto or define an entrypoint element to deploy successfully.

So I updated my app.yaml:

runtime: nodejs12

handlers:
- url: /.*
  secure: always
  script: auto

... more handlers here ...

which deploys successfully.

Try adding a space for any sub item. PHP uses the same parser as python. In python white space is used to denote blocks.

application: phpmyadmin2121
version: phpmyadmin
runtime: php
api_version: 1

handlers:
- url: /(.*\.(ico$|jpg$|png$|gif$))
  static_files: phpMyAdmin/\1
  upload: phpMyAdmin/(.*\.(ico$|jpg$|png$|gif$))
  application_readable: true

- url: /(.*\.(htm$|html$|css$|js$))
  static_files: phpMyAdmin/\1
  upload: phpMyAdmin/(.*\.(htm$|html$|css$|js$))
  application_readable: true

- url: /(.*\.(php$))
  script: phpMyAdmin/\1
  secure: always
  login: admin

- url: /(.+)
  script: phpMyAdmin/index.php
  secure: always
  login: admin

- url: /
  script: phpMyAdmin/index.php
  secure: always
  login: admin
