Following up on this error:
https://github.com/web3privacy/data/actions/runs/10602350927/job/29384187270
Investigated to find that the error was because the caption entry of a speaker had many URL links within then, so breaking the configuration - added the following regex to the pattern for caption:
```
'^((([A-Za-z]{3,9}:(?:\/\/)?)(?:[-;:&=\+\$,\w]+@)?[A-Za-z0-9.-]+|(?:www.|[-;:&=\+\$,\w]+@)[A-Za-z0-9.-]+)((?:\/[\+~%\/.\w-_]*)?\??(?:[-\+=&;%@.\w_]*)#?(?:[\w]*))?)'
```
Tested the regex expression in https://regex101.com/ first to ensure it worked with url format
