Amplify-cli: How to rebuild graphql schema?

[OskarKaminski]

Which Category is your question related to?
API
What AWS Services are you utilizing?
AppSync
Provide additional details e.g. code snippets
OS: OS X 10.13.4

Reproduction steps:

1. Run amplify add api with the following options
   ? Please select from one of the below mentioned services GraphQL
   ? Provide API name: squadhealthcheck
   ? Choose an authorization type for the API: API key
   ? Do you have an annotated GraphQL schema: No
   ? Do you want a guided schema creation: true
   ? What best describes your project: One-to-many relationship (e.g., “Blogs” with “Posts” and “Comments”)
   ? Do you want to edit the schema now: No
2. Update amplify/backend/api/schema.graphql
3. Run amplify push

Current result
Both GraphQL queries, mutations, subscriptions, and DynamoDB tables are created for the default schema (before changes)
The files inside amplify/backend/api/build/ are not updated as well.

Expected result
Both GraphQL and DynamoDB are setup according to the updated schema from the file amplify/backend/api/schema.graphql

[yuth]

If you want to update the graphql schema, you can edit amplify/backend/api/schema.graphql and run amplify api push command. This should update the DynamoDB tables and graphql statements.

Please fell free to re-open the issue if you're still facing problems when updating the schema or need more clarification.

[OskarKaminski]

As you can see in my reproduction steps, I do it. And it doesn't work.

I inspected the code and noticed, that probably compile schema from amplify-provider-cloudformation/lib/utility-functions.js would do the trick with compliling graphQL schema.

I've also found out, compile schema method should be runned when I run amplify api configure command. So I did it, and I got an error:

? Please select from one of the below mentioned services: GraphQL
The selected resource is not managed using AWS Cloudformation. Please use the AWS AppSync Console to make updates to your API - squadhealthcheck
Error: Error updating resource
    at updateWalkthrough (/Users/oskarkaminski/.nvm/versions/node/v9.8.0/lib/node_modules/@aws-amplify/cli/node_modules/amplify-category-api/provider-utils/awscloudformation/service-walkthroughs/appSync-walkthrough.js:211:13)
    at <anonymous>
    at process._tickCallback (internal/process/next_tick.js:118:7)
There was an error updating the API resource

[OskarKaminski]

@yuth I can't reopen the issue...

[kaustavghosh06]

You can try using the ‘amplify api gql-compile’ command?

[OskarKaminski]

@kaustavghosh06 I've tried amplify api gql-compile as well. It doesn't do anything. No output in the terminal. Also no change in the files.

[OskarKaminski]

The issue lays in the
amplify-category-api/provider-utils/awscloudformation/service-walkthroughs/appSync-walktrough.js
In the 208 line the conditional statement resource.provider !== providerName is true.
providerName has value awscloudformation, while resource.provider has value squadhealthcheck which is the value I provided as an API name.
Any ideas why?

[kaustavghosh06]

@OskarKaminski I've root caused the issue. Sending a fix for it ASAP (within the next few hours). in the meanwhile to unblock yourself you could use the CLI version 0.1.24 to compile your schema.

[OskarKaminski]

Thanks a lot @kaustavghosh06

[kaustavghosh06]

@OskarKaminski Just published the fix to NPM. Please install the latest version -> 0.1.27

[OskarKaminski]

Thanks @kaustavghosh06. The fix solved the issue. amplify api gql-compile compiles the schema, and print out the info to the console. I guess amplify api push will compile now as well.
Great job!

[mkaschke]

@yuth - I guess this issue still exists! After editing amplify/backend/api/schema.graphql and running amplify api push command nothing happends and there are changes in the schema in the aws AppSync console.

amplify --version: 0.1.35

[yhenni1989]

the issue still exists in amplify version 0.1.35

[YikSanChan]

@mkaschke @jtaylor1989 can you confirm that amplify ls show api has provider plugin as awscloudformation?
Refer #565 for details.

[mkaschke]

@YikSanChan - it shows the same table as the status table. About the issue: After I deleted the whole stack in aws cloudformation and start from amplify init, add API ... the push works but I don't know why.

[yuth]

@YikSanChan - it shows the same table as the status table.

Could you paste the output of the table (by chance if you have it)

[akroll1]

Currently having the same issue. Any fixes for this?

gql-compile is not working, amplify api update not working, no tables are updated in dynamo...very frustrating. amplify api will not update, just stopped working.

[PerrySong]

I guess the bug might still be there

[vinhtnguyen]

Just want to say that "amplify push" works for me today. I edited schema.graphql file and saw that the changes are reflected in AppSync Console.

[Tuuleh]

I've made updates to amplify/backend/api/schema.graphql. Issuing amplify push results in 'No changes detected'. Running amplify api gql-compile resets the file to how it was before my changes. This is with amplify -v 4.13.2

If I issue amplify ls, it detects the changes to Api. but if I issue amplify push, it seems to first pull, overrides my changes, and then tries to push, resulting in no changes?

@Tuuleh I had the same issue. Just make sure you're making changes in /backend/api/schema.graphql and not /#current-cloud-backend/api/schema.graphql

[Tuuleh]

@WarrenMT I was modifying /backend/api/schema.graphql and don't quite recall how I resolved this in the end. I might have abandoned that environment and used a different one.

[scottkelso]

I am also experiencing this issue. I.e. having created a graphql API...

I then go in to change the schema, and run amplify api gql-compile

D:\Josh\Documents\Projects...>amplify api gql-compile
Scanning for plugins...
Plugin scan successful

GraphQL schema compiled successfully.

Edit your schema at D:\Josh\Documents\Projects...schema.graphql or place .graphql files in a
directory at D:\Josh\Documents\Projects...

I can see the file changes,

D:\Josh\Documents\Projects...>git status

no changes added to commit (use "git add" and/or "git commit -a")

but when I go to push changes, amplify says there are none!

I have amplify v4.18.1

Update

I have since tried again, only this time I began with amplify pull, then added my change to schema.graphql, and now see my resource show up on amplify status:

D:\Josh\Documents\Projects...>amplify status

Current Environment: dev

Weird!

Great job!

this worked perfect thank you.

[icecreamsandwich]

amplify api gql-compile and amplify push works fine for me.
