i use this code：https://github.com/availproject/avail-substrate-api-sidecar

[yaoyf888]

@kroos47 Do you have the source code of sidecar? I use your avail-substrate-api-sidecar to request block information and report errors. Is there any version to solve this problem?

[yaoyf888]

@QEDK Can you help me?

[kroos47]

@yaoyf888 Are you running the sidecar locally?(like building from source and not docker), If yes did you add the avail specific types which is in the root of the repo and the url to the env? If you did all these above steps then what was the request that you were trying?

[yaoyf888]

I do want to run sidecar using the source code, but get an error when requesting block details. How do I add the avail type and env url in the repo root directory? I am currently using docker pull availj/sidecar-api:zenitsu, this docker is OK

[kroos47]

so try to add the files to the .env file or so export SAS_SUBSTRATE_URL=wss://mainnet-rpc.avail.so/ws and export SAS_SUBSTRATE_TYPES_BUNDLE="<_path_to_types.json_files_in_local_repo_"

[yaoyf888]

docker pull availj/sidecar-api:zenitsu Is this available on the mainnet? Will that be a problem?

[kroos47]

yes it is available on the mainnet! But make sure you pass URL and Types when running

[kroos47]

@yaoyf888 let me know if its resolved the issue

[kroos47]

closing this for now!
