[Zvelo]: Connector stops working if data is invalid or incorrectly formatted

[romain-filigran]

Description

We've observed that some of the indicators provided by Zvelo can be incorrectly formatted, causing the connector to stop with the following exception (the problem comes from the URL formatting).
