Hello @pratik gaikwad

Could you please share the notebook path (full string) that is passed to dbutils.notebook.run?

I just copied all the cells from same notebook and created a new notebook with same name at same location (no path changed)

removed old notebook

it worked .

first i tried to clone the notebook but it was giving same error.

and the error occurred unexpectedly my job was live it was working and then sudden error (no changes)

for time being i was able to get above way around but don't know the actual reason of error

Not sure of @pratik21 , but for me cloning the notebook at a different location worked for me and it stopped giving me the error altogether.

Since you're using dbutils.notebook.run() properly now, the issue is not in your current notebook, but actually in the target notebook you’re calling.

Specifically, Databricks is trying to parse a %run command in that notebook, and it’s hitting a syntax error that looks like this:

Failed to parse %run command: string matching regex '\$[\w_]+' expected but 'e' found.
