i’m trying to compose the .net core 5.0 and Sql server. i’m getting the below error

Attaching to webapisqlserver_code_1, webapisqlserver_api_1
api_1 | Could not execute because the specified command or file was not found.
api_1 | Possible reasons for this include:
api_1 |
**** You misspelled a built-in dotnet command.***
api_1 | * You intended to execute a .NET program, but dotnet-WebApiSQLServer.dll does not exist.
api_1 | * You intended to run a global tool, but a dotnet-prefixed executable with this name could not be found on the PATH.
