Error Codes

Invalid JSON

This can happen when your request is malformed. Additionally, some of the provides use this code to signal that a particular method is not available or requires switching to a paid tier.

This usually happens when the method is not available with a given provider. If you need to use a specific method that's not supported by the provider, try changing the provider or consider switching to a more expensive tier.

This happens when the request parameters are invalid. To fix, double check the parameters that you pass with the request and make sure they comply with the spec.

This might happen when the node reverts during the request execution. This can also happen if the request is malformed or invalid.
