Hi @Sunilkumar k ,

Welcome to the community. 

1) you can update custom field value when the automation rule runs. There is an option called edit issue in the actions. you can update custom field value using this. Or you can update custom field value in a transition also.

As per my knowledge,  there is no trigger for attaching in automation.

Hi Sreenivasaraju,

Can you please help me with the syntax of regular expression for adding the new value to the custom field.

For example : i want to display the mime type of attachment in the custom field if the type of attachment given by user is not exe , if the attachment is of exe type then i need to display the custom message in the custom field.

Iam able to display the mimetype of attachment in the custom field , but i want to give the custom message in the custom field when the attachment type is exe can you please help me with the regular expression

Hi Sreenivasaraju p,

Can you please help me with the syntax of the regular expression that we give in the edit issue action to add the value in custom field.

I am also interested in the correct syntax for updating Custom Fields per automation as they do not appear in the dropdown.
