Summary	0007538: request to origin https://exchange.demo.taler.net was throttled
Description	The exchange throttled my transaction, so i get errors in the wallet. This happens with large amounts like 5000 KUDOS and more. The transfer continues and finishes successful. Error: There was an error trying to complete the transaction withdrawal did not finish (797 / 1000 coins withdrawn) { "code": 7015, "hint": "withdrawal did not finish (797 / 1000 coins withdrawn)", "errorsPerCoin": { "107": { "code": 7004, "hint": "request to origin https://exchange.demo.taler.net was throttled", "requestMethod": "POST", "requestUrl": "https://exchange.demo.taler.net/reserves/AXGHSQHRN2FQDJ1N9RTRH93AZ42P8545CAPH0D276WAXSE6VGVBG/withdraw", "throttleStats": { "tokensHour": 1893.0020347222235, "tokensMinute": 393.1220833333333, "tokensSecond": 0.3250000000001246, "maxTokensHour": 2000, "maxTokensMinute": 500, "maxTokensSecond": 100 } }, "108": { "code": 7004, "hint": "request to origin https://exchange.demo.taler.net was throttled", "requestMethod": "POST", "requestUrl": "https://exchange.demo.taler.net/reserves/AXGHSQHRN2FQDJ1N9RTRH93AZ42P8545CAPH0D276WAXSE6VGVBG/withdraw", "throttleStats": { "tokensHour": 1893.002036666668, "tokensMinute": 393.12219999999996, "tokensSecond": 0.3320000000001246, "maxTokensHour": 2000, "maxTokensMinute": 500, "maxTokensSecond": 100 } }, "109": { "code": 7004, "hint": "request to origin https://exchange.demo.taler.net was throttled", "requestMethod": "POST", "requestUrl": "https://exchange.demo.taler.net/reserves/AXGHSQHRN2FQDJ1N9RTRH93AZ42P8545CAPH0D276WAXSE6VGVBG/withdraw", "throttleStats": { "tokensHour": 1893.002037777779, "tokensMinute": 393.12226666666663, "tokensSecond": 0.3360000000001246, "maxTokensHour": 2000, "maxTokensMinute": 500, "maxTokensSecond": 100 } },
Additional Information	withdrawal did not finish (797 / 1000 coins withdrawn) You can show a progress bar with this data ;) A solution would be to have less coins. That would be possible if coins have a greater value, like 1000 KUDOS.

Florian Dold 2023-02-10 14:59 manager ~0019797	That's expected and more of a bug than a feature! The wallet is allowed to make at most 100 request per second, 500 per minute and 2000 per hour for a particular exchange. With the new batched withdrawals (just implemented), the request throttling should not kick in as soon when doing bigger withdrawals. But it will still kick in for really big ones, and that's intended.
