Usage notes¶

To avoid affecting files in the application’s source stage, this command uses the scratch_stage of the application package entity to create a blank stage, to upload project files to this stage, to run validation, and to drop the stage.

Validation returns errors and warnings separately. Errors cause the command to exit with an exit code of 1, but warnings do not.

Examples¶

The following example shows the output for a successful validation:

snow app validate

Copy

Validating Snowflake Native App setup script.
  Checking if stage st_version_pkg_<user>.app_src.stage_snowflake_cli_scratch exists, or creating a new one if none exists.
  Performing a diff between the Snowflake stage and your local deploy_root ('<APP_PATH>/apps/st-version/output/deploy') directory.
  There are no new files that exist only on the stage.
There are no existing files that have been modified, or their status is unknown.
There are no existing files that are identical to the ones on the stage.
New files only on your local:
README.md
manifest.yml
setup_script.sql
streamlit/environment.yml
streamlit/ui.py
  Uploading diff-ed files from your local <APP_PATH>/apps/st-version/output/deploy directory to the Snowflake stage.
  Dropping stage st_version_pkg_<user>.app_src.stage_snowflake_cli_scratch.
Snowflake Native App validation succeeded.

The following example shows the output for a successful validation, using the JSON output format:

snow app validate --format json

Copy

{
    "errors": [],
    "warnings": [],
    "status": "SUCCESS"
}

The following example shows the output when the validation encounters errors and warnings, using the JSON output format:
