Variable Transform in chains: Replace text error

Respondida
Solicitar demostración

Hello,

I am building a chain to extract a document to DOCX using Workiva API.

At the second step of the chain, Workiva returns in the HTTP Header the Location (i.e. URL) of the file in a JSON format that looks like this 

"Location":["https://api.eu.wdesk.com/platform/v1/operations/XXX"]

I want to get rid of the [" and "] to retrieve the clean URL for the next step of the chain.

I tried multiple way including panning or RegEx but I get similar error. For instance if I try this:

 

I receive the following error: Error building Command: Replace transformation: Invalid value, pattern, match, or replacement provided 

 

Any ideas of how to handle this? 

Thanks

    Did you try escaping the [ character in your RegEx, since it is a RegEx control character?

    If not, you could try something like [\[\]"] as your pattern, where the three characters the Regex will look to replace are [ ] and " and the brackets you're looking for have been escaped with \ inside the RegEx control brackets.

    Hi Ruggero Golini (LU),

    You can retrieve the Location URL value in the GET request by getting the 0th element of the Location array. Below is a screenshot of the transformed Header Response variable from the Initiate a document export POST request.
