[Bug] SyntaxError: Unexpected end of JSON input #2690

dadadan23 · 2021-05-13T21:41:20Z

Describe the bug
In our Azure DevOps Pipeline, we are trying to specify the path to an externalized GitVersion.yaml which is in the Resources repo we also use for ADO templates.

When we specify the configFilePath to the yaml, we receive the error:
##[error]SyntaxError: Unexpected end of JSON input

I can confirm the file is physically available in the working directory and also the GitVersion.yaml works on my local macbook without issues.

We are running on a self-managed linux vm

Expected Behavior

We would expect the extension to be able to take the input for the location where the configuration file is located, read it, and use it during the pipeline duration.

Actual Behavior

We receive an error:
##[error]SyntaxError: Unexpected end of JSON input

Possible Fix

The only workaround we have is to commit the GitVersion.yaml directly into the repo being built.
So far, have not found any way to get an external file to read successfully

Context

We are trying to tune gitversion to provide semantic versions differently than the plugin defaults, so we can control the versioning increment as desired by our organization. Without this, we are getting alpha and beta tags on our releases, which is not desired.

Your Environment

Version Used:
GitVersion Task version: 0.9.9, GitVersion.Tool 5.6.9 x64

ADO agent version 2.184.2
Linux, CentOS 7

Perhaps related to #2567.

cytron201 · 2021-10-29T11:42:53Z

I am having exactly the same issue. Cannot find the .git directory and Unexpected end of JSON.

I've narrowed it down to be because of using the following in the pipeline for the job that calculates version:
- checkout: none
persistCredentials: "true"

Of course by not checking out, it wont even sync to a git repository, so the .git folder stays empty. The reason it was working sometimes and not others for us, was because some of our Azure DevOps agents still had the workspace mapped from a previous build of the same repository (pre breaking changes), therefore meaning the .git folder was already present.

xsurfer · 2022-01-26T15:03:15Z

I am facing the same issue. Any idea how to solve it or troubleshoot it? Thanks

UPDATE - I manage to solve it: an existing release branch had wrong name (v1.0.0.0). I deleted the branch and the task run successfully

SphenicPaul · 2022-04-14T18:37:49Z

I've hit a similar, error message today - Possible workaround (if related) is to fix/specify the versionSpec to a working version (e.g. 5.9.0) as mentioned in #3007. This seems to have resolved this error for me in the short term.

astro-phage · 2022-08-18T09:02:21Z

Version 5.9.0 didn't work for me with self-hosted agents. Version 5.10.1 does work for me. See also [Bug] Version 5.10 is causing "SyntaxError: Unexpected end of JSON input" error

Example azure-pipelines.yml

steps:
  - task: gitversion/setup@0
    inputs:
      versionSpec: '5.10.1'

arefworks · 2022-09-10T06:16:09Z

Im using version 5.10.3 and im getting the same issue

I've hit this issue again today on GitVersion v5.9.0 and also tried v5.10.3 (and an older v5.7.0) - All hit the Unexpected end of JSON input error.

Oddly, I've only hit this issue on a couple of repos that I've created today in Azure DevOps Services - Other builds that were using GitVersion v5.9.0 were working OK and have been for a while since my previous post in this thread.

Given that it only seemed to be impacting the new repos and the error message also seemed to state that it couldn't find the initial/first commit, I'd been able to create a new repo in Azure DevOps, initialize it locally/offline then push a commit back to the remote, Azure DevOps repo - I noted that GitVersion did work sucessfully in the build on the initial/single commit, but then failed once a second commit was added to the master branch.

I'm not clear how to resolve this for these new repos at present, and am unclear why this isn't also impacting the older/existing repos that use the same build templates that make use of the same version of GitVersion (existing repos/builds work on v5.9.0 and v5.10.3, but new repos fail on both).

I can only think it's something in GitVersion potentially not supporting a later/newer version of Git, perhaps (I'm now using Git 2.37.2.windows.2 locally and Azure DevOps, hosted build pool is using Git 2.37.3), but possibly steming/caused from/by the initial creation/initialization of the repo, rather than something post-creation...not sure?!

Any help/suggestions would be appreciated.

@SphenicPaul, the argument --depth=1 makes the repository being cloned a shallow clone, which will cause GitVersion to crash. When GitVersion crashes and outputs an exception instead of valid JSON, the AzDO Task and GitHub Action will mask the error by instead throwing the Unexpected end of JSON input error. Please see #3091 (comment) for how to do a full clone in AzDO.

SphenicPaul · 2022-09-11T06:42:37Z

Thanks @asbjornu - that link and solution has been able to resolve/workaround the problem I was hitting.

Much appreciated.

asbjornu · 2022-09-11T20:27:05Z

I'm glad @SphenicPaul. As this is a bug in the task/action and not within GitVersion itself, I'm closing in favor of GitTools/actions#730.

humberto-fanatee · 2022-09-14T14:25:54Z

Even though this ticket is closed, I'd like to share a task definition that solved the issue for me:

- task: CmdLine@2
  inputs:
    script: 'git fetch --unshallow --update-shallow'

Be sure to use persistCredentials: "true" in the checkout step so that the git command can run.
