findTransactionSignature() not finding the transaction by the provided reference

[mortiet]

Hey guys. I am testing solana pay to build a payment module based on it but I haven't been able to successfully finalize a payment based on the payment-flow-merchant example! Steps that I follow:

1. Successful connection to devnet

   Connection to cluster established: https://api.devnet.solana.com { 'feature-set': 3246413280, 'solana-core': '1.9.9' }

2. Simulate Checkout using my test merchant wallet and generate the payment URL:

   solana:GrH51Zbp6czGypTUe2gcU6B6eB9BjTERx7K6XYoXE9au?amount=0.01&reference=4ZQAj72fPDzy99UNWZdupTd5rKMeoXn7r1nguzT5hxKA&label=MORTIE-PAY&message=MORTIE-PAY%20-%20your%20order%20-%20%23001234&memo=JC%234098

3. I then convert the URL to QR code and scan it with my second test wallet made on Slope Wallet (Android) while the network is set to devnet. Transaction succeeds and gets fully confirmed. I can see the reference and the message added to the URL shown while approving the transaction on my wallet. https://solscan.io/tx/5TukQF9AEYjf7oDdPxpP7Bc6nNezzcANt8ooa5ztT8t36S4yfX8opmsLJYwwwxS8aQhwSYXSjFFBzgHL4dEiYgiy?cluster=devnet
4. Now at this stage, findTransactionSignature() never finds the transaction using the randomly generated reference key. I can't actually see this transaction using the reference on Solscan as well.

Can you help me with this, please? Should I find that reference key somewhere in the transaction description in Solescan? Thank you!

Ah, this is an issue with Slope. Their wallet is not including the reference field in the transaction. I've reported this to them!
