Cannot pass binary metadata headers for gRPC requests

When trying to query a gRPC method, I'm unable to propagate metadata headers that are of binary format. It seems like only String type metadata values are allowed.

Hey there, thanks for reaching out! Confirming here that currently binary metadata isn't supported -- only strings are. We have written up a feature request internally to add support for gRPC binary metadata and I have linked that request to this thread so that I can update you when progress is made :slightly_smiling_face:

Hi @lauren.gus, we require this feature too, any update?

Ideally we'd like to be able to collect a specific metadata value from another query/form and be able to binary attach it to the request's metadata.

Thank you.

Hey @pedroc :wave: No progress update at the moment, but appreciate you reaching out and sharing your use case! Will share updates here when we have them :slightly_smiling_face:

Hi @lauren.gus, do you have an estimate as to when and whether this feature will ever be supported?

@lauren.gus Any updates on this? Would love to be able to use retool but this is blocking us unfortunately.
