How do I fix COPY INTO (Stage Not Found)?

List available stages: SHOW STAGES IN SCHEMA mydb.myschema. Use a fully-qualified stage reference: @mydb.myschema.mystage. Grant USAGE on the stage to the executing role: GRANT USAGE ON STAGE mydb.myschema.mystage TO ROLE my_role. For external stages, verify cloud storage credentials are still valid: DESC STAGE @mydb.myschema.mystage. If the stage was accidentally dropped, recreate it with the original storage URL and credentials

Power BI Refresh Error:
COPY INTO (Stage Not Found)

What does this error mean?

The COPY INTO command cannot locate the specified stage. The stage name is invalid, the stage was dropped, or the executing role lacks USAGE privilege on the stage.

Common causes

1Stage name is misspelled or uses the wrong prefix (@myschema.mystage vs @mystage)
2The stage was dropped or belongs to a different schema than the current session context
3The executing role lacks USAGE privilege on the stage
4An external stage's cloud storage URL or credentials were changed, causing Snowflake to mark it invalid
5The stage was created in a different Snowflake account or database

Frequently asked questions

What is the difference between an internal and external stage in Snowflake?

Internal stages store files within Snowflake's managed storage. External stages point to cloud storage (S3, Azure Blob, GCS) you control. External stages require valid cloud credentials and can fail independently of Snowflake if those credentials expire.

Can I recover files from a dropped internal stage?

No — dropping an internal stage permanently deletes the staged files. Unlike tables, stages are not covered by Time Travel. Ensure critical staging areas are protected from accidental drops with appropriate access controls.
