Invalid Figure Field when using API

Coming across this in few different ways when making docs and noticed it raised in the community forum too.

When using scattercarpet type script below, I kept receiving the error:

Error: Client error: (400) Bad Request Figure field is invalid. Reason: Raw data arrays are not allowed at this endpoint. Use grid references instead. Raw data found at the following paths in the figure [('data', 1, u'y')]

p <- plot_ly(
    type = 'carpet',
    a = c(4, 4, 4, 4.5, 4.5, 4.5, 5, 5, 5, 6, 6, 6),
    b = c(1, 2, 3, 1, 2, 3, 1, 2, 3, 1, 2, 3),
    y = c(2, 3.5, 4, 3, 4.5, 5, 5.5, 6.5, 7.5, 8, 8.5, 10),
    aaxis = list(
      tickprefix = 'a = ',
      ticksuffix = 'm',
      smoothing = 1,
      minorgridcount = 9
      ),
    baxis = list(
      tickprefix = 'b = ',
      ticksuffix = 'Pa',
      smoothing = 1,
      minorgridcount = 9
      )
    ) %>%
  add_trace(
    type = 'scattercarpet',
    a = c(4, 4.5, 5, 6),
    b = c(2.5, 2.5, 2.5, 2.5),
    line = list(
      shape = 'spline',
      smoothing = 1,
      color = 'blue'
    )
  )

api_create(p)

Comienza reproduciendo el ejemplo proporcionado de R con plot_ly(), add_trace() y api_create(), centrándote en el trace scattercarpet y en el error de validación de datos sin procesar informado. Lee la ruta de validación o serialización de Figure de la API que gestiona estas llamadas; el trabajo estará terminado cuando la API acepte el ejemplo sin el error de campo Figure no válido.
