btcpayserver: System.Exception: Unable to load bundles (HTTP 500 on initial load web UI)

After successful installation and startup of BTCPay server, an error occurs the first time I try to access the web UI on port 23001. HTTP 500 is returned to the web client and a System Exception occurs in the btcpay logs (logs at the end of this issue)

Version of BTCPay Server: v1.0.3.88 (also failing for several other 1.0.3.xx versions tested)
Deployment method: Manual Build
Other relevant environment details: Ubuntu 16.04

To Reproduce

Build and run BTCPay from systemctl startup script
BTCPay uccessfully connects to NBXplorer and sees new blocks
BTCPay starts HTTP server on 23001
On initial HTTP get of localhost:23001, HTTP500 is returned.
Logs show system exception in LoadBundles()

Additional details:

BTCPay server is running as a non-administrative user.
daemon user and group have full access to the btcpayserver build and launch directory
It worked before “bundles”
Crash happens even when bundlejscss is set to false
Additional logging added to the code shows that bundlejscss is correctly read as “false” in the daemon execution.
Daemon user has full file access to bundleconfig.json
Even when setting 777 permisions on bundleconfig.json, it still crashes

Update bundle minifier, trying to fix (#710 with bundle on) — committed to btcpayserver/btcpayserver by NicolasDorier 5 years ago

I managed to isolate the problem to the systemd start script. I copied from the run.sh contents and this command line worked:

ExecStart=/usr/bin/dotnet run --no-launch-profile --no-build -c Release -p "BTCPayServer/BTCPayServer.csproj" --conf /data/btcpayserver/btcpayserver.conf --datadir /data/btcpayserver/

The problem was all in how I launched BTCPay from systemd. I had copied the systemd from one of the tutorials, and it didn’t work.

Yep, I confirm it works for me now. 😃 @aantonop if you use bundlejscss to true (as it should be normally), you won’t have permission issue as I read the bundle.config directly from the resources of the assembly.

So are you now:https://i.giphy.com/media/Ae7SI3LoPYj8Q/giphy.webp ?

@aantonop I tried brand new VM, manual install and it just worked.

Install Bitcoin Core 0.17.0

BITCOIN_VERSION="0.17.0"
BITCOIN_URL="https://bitcoincore.org/bin/bitcoin-core-0.17.0/bitcoin-0.17.0-x86_64-linux-gnu.tar.gz"
BITCOIN_SHA256="9d6b472dc2aceedb1a974b93a3003a81b7e0265963bd2aa0acdcb17598215a4f"

# install bitcoin binaries
cd /tmp
wget -O bitcoin.tar.gz "$BITCOIN_URL"
echo "$BITCOIN_SHA256 bitcoin.tar.gz" | sha256sum -c - && \
mkdir bin && \
sudo tar -xzvf bitcoin.tar.gz -C /usr/local/bin --strip-components=2 "bitcoin-$BITCOIN_VERSION/bin/bitcoin-cli" "bitcoin-$BITCOIN_VERSION/bin/bitcoind"
rm bitcoin.tar.gz

Install .NET Core SDK 2.1: On my ubuntu 16.04: (See those instructions for different OS).

wget -q https://packages.microsoft.com/config/ubuntu/16.04/packages-microsoft-prod.deb
sudo dpkg -i packages-microsoft-prod.deb
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install -y dotnet-sdk-2.1

Install NBXplorer

cd ~
git clone https://github.com/dgarage/NBXplorer
cd NBXplorer
git checkout latest
./build.sh

Install BTCPayServer

cd ~
git clone https://github.com/btcpayserver/btcpayserver
cd btcpayserver
git checkout latest
./build.sh

Run bitcoind:

bitcoind

Run nbxplorer:

cd ~/NBXplorer
./run.sh

Run BTCPayServer:

cd ~/btcpayserver
./run.sh --port 8080 --bind 0.0.0.0

Now you can browse your server on port 8080.

Can you repro this?

NicolasDorier on Mar 29, 2019

OK, missing reference to BundlerMinifier.Core was what was causing the problem in some cases I guess:

https://github.com/btcpayserver/btcpayserver/commit/0578a692db119a4297ff168009fb46a77664382b#diff-6a9de8749b532027dc48bb5be3e83b03R39

If you pull and build with this latest commit @aantonop - it should work. Plus with fix @NicolasDorier has provided, we are now good with upgrading to .NET Core 2.2 when it’s time. ❤️
