I'm using Zoho data prep to ingest data from One Drive into Zoho Analytics...
The pipeline is super simple but I can't any way to get all the files that I need. Basically I need to bring all the files with a certain pattern and for that I'm using a regex expression on the source configuration.
My files are called with this format YYYYMMDD_HHMMSS_CONTACT and YYYYMMDD_HHMMSS_ACCOUNT_CONTACT

For example
20241115_050104_CONTACT
20241106_050120_CONTACT

20241003_050129_ACCOUNT_CONTACT

20240918_112048_ACCOUNT_CONTACT 

The pattern for ACCOUNT_CONTACT is working perfectly with .*ACCOUNT_CONTACT.json

But I can't use the same strategy for CONTACT because it will bring also ACCOUNT_CONTACT, so I tried to validate that the previuos character is numeric but it's not working as expected.

Also I tried a different pattern to match with the format YYYYMMDD_HHMMSS like this 

[0-9]{8}_[0-9]{6}_CONTACT.json

The weird part is but scenarios are able to read some files but it ignore the majority.

I will appreciate ideas about why it can be block because I'm really stuck with this.

thanks in adavence!!
