@Redni Can you show me the line 18 in the Letter.js controller? It should be

const data = await strapi.services.letter.fetchAll(ctx.query);

So, do you have a Letter.js service in ./api/letter/services/Letter.js?

[oritwoen]

@Aurelsicoko I discovered a problem. To tell the truth, the previous name was different, I changed it for these logs because I did not want to share a unique name so it was not used publicly. It turned out that I missed a significant problem.

When adding "New Content" in the admin panel, any type of name:
strapi.api
test.api

are automatically converted to:
strapiApi
testApi

then we have:

./api/strapiapi/controllers/StrapiApi.js
./api/strapiapi/models/StrapiApi.js
./api/strapiapi/services/StrapiApi.js

The appeals are as follows:

const data = await strapi.services.strapiApi.fetchAll (ctx.query);

So to summarize. Names that only consist of lowercase work perfectly. These consisting of small and large do not work at all.

Okay thank you for this issue, generated code is not completely correct.
The global model have to be Strapiapi or Testapi instead of StrapiApi
And in strapi object it's strapi.services.strapiapi or strapi.models.strapiapi instead of strapi.models.strapiApi.
