Solana error: Missing platform fee account (0x1773)
The route expected a platform fee account that was not supplied, so the swap was rejected before executing.
Why it happens
- The integrator's fee account was not created or not passed in.
- You are calling the aggregator directly without the account list the interface normally builds.
- A white-label front end has a misconfigured fee wallet.
How to fix it
- Use the official interface for that aggregator.
- Create the fee account first if you are integrating.
- Remove the platform fee parameter if you do not need it.
