Hi @Aviral-Bhardwaj 

Looking at this error, it's an InvalidMountException related to Unity Catalog Volumes. Try below:

Check Volume Path and Permissions:

# First, verify the volume exists and check permissions
dbutils.fs.ls("/Volumes/mydatabricksaviral/datatesting/datavolume/")

# Check if the specific file exists
dbutils.fs.ls("/Volumes/mydatabricksaviral/datatesting/datavolume/mytest.json")

Grant Proper Permissions

-- Run this SQL to grant permissions on the volume
GRANT ALL PRIVILEGES ON VOLUME mydatabricksaviral.datatesting.datavolume TO `your_user_or_group`;

-- Check current permissions
SHOW GRANTS ON VOLUME mydatabricksaviral.datatesting.datavolume;

Most Common Fixes:
Permission issue: Run the GRANT statement above
Volume not mounted: Restart the cluster
Path format: Try different path formats
File doesn't exist: Verify with dbutils.fs.ls()
