Hello all,

I've been scratching my head on the below, perhaps any of you has run into this issue or knows what is wrong?

When i run:

cds add http

I get the following error message. Please note that I redacted the username and project folder in the output (indicated with **).

PS C:\Users\**username**\code\**project name**> cds add http --filter ManagementService

Hi @Nicolaas ,

It seems like a bug in @sap/cds-dk.

I managed to fix it locally by adding the following line to as-json.js right before the line where the crash happens (#62):

if (!data[name]) continue

so the fragment will looke like:

    for (let i = 0; i < numRecordsToGenerate; i++) {
      fillRecord(records[i], idNum+i, entity, csn, data, null, 0, referenceData)
    }
    if (!data[name]) continue
    data[name] = data[name].concat(records) // append the new records to the possibly existingand referenced records
    // remove records w/ duplicate keys. This can happen if the key is an enum (and we have less enum values than requested records).
    data[name] = uniqRecords(data[name], entity)

In your case the path for as-json.js is C:\Users\**username**\AppData\Roaming\npm\node_modules\@sap\cds-dk\lib\init\template\data\as-json.js, you can navigate there from VSCode terminal by Ctrl+Click (or Cmd+Click in Mac)

Peter
