"endowment:network-access" permission requested, but fetch in library fails

[compojoom]

I'm playing around with snaps. I've set "endowment:network-access" as initialPermission and I've granted it to the snap

When I do fetch(....) inside of the main entry point - it is all fine - the fetch succeed. But if I try to call a library that on it's own calls fetch it fails.

I'm doing this call:

const allDeployedCurrencyNetworks = await tlbc.currencyNetwork.getAll()

which in terms calls this:
https://github.com/trustlines-protocol/clientlib/blob/14c99652df01233d7f40e9e39691bebd1fbc773e/src/CurrencyNetwork.ts#L52

which in terms end up with call to this:
https://github.com/trustlines-protocol/clientlib/blob/14c99652df01233d7f40e9e39691bebd1fbc773e/src/utils.ts#L47

The error I get is:

Unhandled Runtime Error
TypeError: Failed to fetch

is there anything special I need to do to enable network permissions to dependencies of the snap?

Oh never mind. I guess I was too tired and had a typo in the specified URL... Granting the "endowment:network-access" gives every package access to fetch.
