More context for syntax not found error

[KenxinKun]

Hi! I'm getting some rather cryptic syntax not found error like below

2024-11-21T10:17:01Z ERR unable to copy file /proto/testdomainservice/v2/service.proto error="proto syntax not found"

As far as I can tell I managed to resolve all the imports, but the error won't give me more information on the specific syntax (i.e. if a message is missing or a proto file can't be imported it's specific about those).

What am I missing? Is there a way to get more context out?

Hello. Thanks for the valuable comment. By mistake, it can't find syntax. Something like this syntax = "proto3";

[KenxinKun]

Hmm that's literally the first line in my proto :)

[rez1dent3]

No, it crashes on a specific file. It could be a regular expression error. If it's not too much trouble, could you attach the file and write what version of gripmock you're using?

[KenxinKun]

Sadly the proto is private :/ The version I'm using is Docker's bavix/gripmock:latest

I have tried "cutting out" messages from the file and with a very minimal one it suddenly worked. I could try to narrow it down to a section of the file and see if I can replicate it with a non-private proto.

[KenxinKun]

Quick update: I think it may have to do with the proto file length: my original file has 2473 lines and after I kept deleting messages, it started passing around ~1000 lines. I will generate some valid but non-sensitive proto to illustrate this and attach it.

[KenxinKun]

Here it is, steps to reproduce:

• Download proto from here https://buf.build/kenxinkun/gripmock-test/file/main:generated.proto (let me know if there's access issues, it should be public)
• cd to the location of generated.proto
• Run docker run --rm -it -v ./generated.proto:/proto/generated.proto:ro bavix/gripmock /proto/generated.proto
• This should fail with proto syntax not found
• Edit the proto file and remove the last message
• Run the docker command again and this time it should just work

@rez1dent3 do let me know if you can reproduce my error or if I can help in any way :)

[rez1dent3]

@KenxinKun Thank you. I'll look at it this weekend or tomorrow.

The new latest build will be ready in 15 minutes, but I recommend you to switch to 3.x-dev.

The latest build gets into latest, the fix is ​​made only for version 3.x, which is not released yet and I continue to make releases of the second version. Which can affect your pipeline.

docker pull bavix/gripmock:3.x-dev

[rez1dent3]

@KenxinKun The build is assembled.

[KenxinKun]

Nice! I'll try as soon as I can :)

When do you plan to officially release v3?

[rez1dent3]

I plan to do it in the first quarter of the 25th year. There is no exact date

Just dropping a note to confirm the fix works with my real protos now, thanks!
