glmer model Error in list2env(data) : first argument must be a named list -

i'm new r , creating models may easy fix.

i using glmer in lme4 package model data: b1 <- glmer(overlap_m ~ 1 + sex_m + fieldseason_m +(1|birdid_m) ,data = overlapdataframe_matrix, family=gamma, start=null)

each of fixed effects , random effect (birdid_m) have been defined as.list created columns of matrix "overlapdataframe_matrix"

 `head(overlapdataframe_matrix)      birdid fieldseason sex  overlap      area [1,]      1      5.2014   1 31.56543 118216.40 [2,]      2      5.2014   1 28.44252  74989.85 [3,]      3      5.2014   1  3.15136  30234.26 [4,]      4      5.2014   1 54.28696  33223.01 [5,]      5      5.2014   1  0.00000  55337.15 [6,]      6      5.2014   1 43.80645  21412.06` 

when run model error: error in list2env(data) : first argument must named list

i have tried different ways change environment each variable in, not clear on how works. issue here, or there easier fix?

the lmer command needs data input defined data.frame

overlapdataframe_matrix <- data.frame(overlapdataframe_matrix)
