How to use regex in ECS task definition JSON?

Question

I'm trying to add awslogs-multiline-pattern to my ECS task definition. For matching timestamp, I'd like to use

```
  "awslogs-multiline-pattern": "^$$([0-9]{2}:[0-9]{2}:[0-9]{2} [A-Z]{3})$$"
```
 but getting " Unexpected token [ in JSON ..." error during deploy. 
I couldn't find a direction for a fix/workaround.

TIA, Vitaly

Answer

Possibly it's treating the escape as a String escape rather than a regex escape?  Perhaps try:

`"^$$([0-9]{2}:[0-9]{2}:[0-9]{2} [A-Z]{3})$$"`

I'm not using this anywhere currently, and I didn't construct a test, so this guess might not pay off, but seems worth a shot.
