Error during withdrawal: must be greater than 0 (bad_request.bad_param.bad_param.amount)

[billettg]

Hi, when attempting a pot withdrawal I'm seeing the below error.

I see the same issue when using 'Monzo Playground' with the same formatted URL.

Any idea how I resolve this?

Sorry for getting back to you so late and thank you for reporting.

It was actually just fixed it in #39 - as found out by @m-roberts, it turns out that certain Monzo API endpoints (including pot withdrawal and deposit) require you send the request data via 'form data' and not 'query params'.

[pawelad]

This should be fixed in the (just released) v2.2.0

Brilliant, thank you.
